Whoa, those government desktops add up quickly.  This Vista ban will immediately effect over 50,000 desktops, with tens of thousands more possibly impacted by the IE 7.0 ban.  The MS Exchange/SharePoint Hub juggernaut is based on IE 7.0, which is not available for Windows 2000 - MSOffice 2000 desktops.

Lack of Vista Stack compatibility with non Microsoft application is given as the reason for the ban.  But notice the "alternatives" to Vista mentioned; Novel SuSE and Apple Mac.  What kind of interop - compatibility do they offer?  My guess is ZERO!

The reality is that the DOT is trapped.  My advice would be stay exactly where they are, keeping the current MSOffice desktop installs running.  Then, install the Foundation's daVinci ODF plugin for MSOffice. 

This will insure that Windows OS and  MSOffice bound business processes can continue to function without disruption.  Win32 APi based applications like those mentioned in the article can continue.  Critical day to day business processes, workgroup and workflow related activities can continue without disruption or costly re engineering demanded by a cross platform port.

What daVinci doe sdo is move the iron triangle that binds Windows-MSOffice applications to business processes and documents, to an ODF footing.  Once on a ODF footing, the government can push forward with the same kind of workgroup - workflow - intelligent docuemnt - collaborative computing advnaces that the Vista Stack was designed to deliver.  Only this push will involve the highly competitive "the customer is sovereign" environment of ODF ready desktop, server, device and Web 2.0 systems.  End of Redmond lock-in.  End of the costly iron triangle and the force march upgrade treadmill that so enriches Microsoft.

So what's not to like?  We can do this.
