The Internet Archice is now offering over one million items as peer to peer BitTorrent downloads. While in one sense it is only a different download method for materials that are copyright and royalty free, it is Torrents have been controversial as they are often used to download pirated movies and software. However, the Internet Archive does have a point in that it improves access for users with limited bandwidth. Downloads include 1.2 million books and 9,000 videos and movies.
This was a concept that I wasn't too sure if it wasn't ready for prime time or was simply a bad idea. Library patrons could sign up for a "Cloud" account and be given a thin client laptop that would access a Windows 7 image via Citrix which is "their" computer to install programs on or use as needed.
However the initial outlay was $300,000 with $5,000 a year ongoing maintenance costs and considerable bandwidth requirements to stream an HD Windows desktop. Further it was limited to only laptops used in the library with a maximum base of 160 users.
I honestly couldn't see this as a good idea because of the cost and limited use. It would be cheaper to rent out laptops and re-image when they are returned.
