A new IETF working group has been proposed in the Real-time Applications and Infrastructure Area. The IESG has not made any determination as yet. The following draft charter was submitted, and is provided for informational purposes only. Please send your comments to the IESG mailing list (iesg at ietf.org) by January 20, 2010. ... According to reports from developers of Internet audio applications and operators of Internet audio services, there are no standardized, high-quality audio codecs that meet all of the following three conditions: 1. Are optimized for use in interactive Internet applications. 2. Are published by a recognized standards development organization (SDO) and therefore subject to clear change control. 3. Can be widely implemented and easily distributed among application developers, service operators, and end users. ... The goal of this working group is to develop a single high-quality audio codec that is optimized for use over the Internet and that can be widely implemented and easily distributed among application developers, service operators, and end users. Core technical considerations include, but are not necessarily limited to, the following: 1. Designing for use in interactive applications (examples include, but are not limited to, point-to-point voice calls, multi-party voice conferencing, telepresence, teleoperation, in-game voice chat, and live music performance) 2. Addressing the real transport conditions of the Internet as identified and prioritized by the working group 3. Ensuring interoperability with the Real-time Transport Protocol (RTP), including secure transport via SRTP 4. Ensuring interoperability with Internet signaling technologies such as Session Initiation Protocol (SIP), Session Description Protocol (SDP), and Extensible Messaging and Presence Protocol (XMPP); however, the result should not depend on the details of any particular signaling technology.

W3C releases CSS Selectors Level 3 as Proposed Recommendation.

Playing with the software now. Unite is a cloud integration, with a directory on your system identified as a directory to be shared with the cloud storage. Haven't really got into it yet, but I see options to keep the data in the folder private, to share it with those who know the password, and to publish the directory to the world. There are roughly 25 Unite applications not discussed in the press release here. http://unite.opera.com/applications/ My first thought was that Google will have to respond in kind, while Microsoft --- which doesn't get the power of "free" --- will respond but with a less generous offering.

Opps. I was wrong. There is no online storage. It is as stated in the press release, an integration of a server with the Opera browser. The shared content is served by the local machine. Which means that the local machine must be running in order for others to access the shared content. But according to the Unite FAQ, this also means that there are only practical limits on the amount of content shared, e.g., hard disk capacity and bandwidth. Why bother with setting up a LAN or VPN if you can share files over the internet using Opera? And how will Google and Microsoft respond?

Microsoft last week launched its first serious effort to build IT into its cloud plans by introducing technologies that help connect existing corporate networks and cloud services to make them look like a single infrastructure. The concept began to come together at Microsoft's Professional Developers Conference. The company is attempting to show that it wants to move beyond the first wave of the cloud trend, which is defined by the availability of raw computing power supplied by Microsoft and competitors such as Amazon and Google. Microsoft's goal is to supply tools, middleware, and services so users can run applications that span corporate and cloud networks, especially those built with Microsoft's Azure cloud operating system.

An important insight from Tim O'Reilly.

Kurt Cagle digs into audio and video support in HTML 5. As always, his view is revealing.

My initial impression is that this is not good news, that this is a further sign of W3C abandonment of XHTML. The announcement that the WG will be closed by implication means that all CDF WG projects are coming to a standstill. The CDF WICD profiles currently have no profiles developed for spreadsheets and presentations albeit feature-rich enough to serve for web display of presentations. WICD profiles are at version. 2.0, with each 2.0 profile a superset of the 1.0 profiles. They are feature-lean in comparison to desktop word processors. The Compoound Document by Incorporation Framework  is an even more immature document, not nearly ready for prime time. All of which suggests that the Compound Document by Reference Framework itself may be the only WG work product with a shot at survival. HTML 5 and browser quirks mode wins; the world loses. Blech!

The ripples from the European Commission v. Microsoft decision continue to flow. The catch, of course, is that the patent rights will almost certainly be subject to the Microsoft Open Specification Promise, a weasel-worded document that actually grants no rights. http://law.bepress.com/unswwps/flrps/art71/ But someone with some clout will push that issue sooner or later.
