The hot buttons at the moment in the industry is "on demand" and SOA "service orientated architectures"

with these in mind and adding a few of these bits together, VDI (virtual desktop infrastructure) becomes reality 
Virtual Server, VISTA, Windows 2003 or Longhorn, so why use Terminal Services or Citrix, all the normal problems
of deploying applications and users not understand about running on a Server Based Computing environment.

Looking into a VDI (virtual desktop infrastructure) life may become easy (easier) for solutions using the of running
Windows XP or Vista on a Virtual server via RDP, and hosting / deploying applications via Softricity or via published
applications from specific silo’d Terminal Services / Citrix or deploy native means, being able to add and remove the
applications when needed and not worrying compatibility about integration on each desktop.

The only bit of the puzzle that seems to be missing is a authentication broker to assign desktops and applications,
oh yea Softricity (now part of Microsoft) has that for applications part already, just need something for the login
authentication such as Citrix Web Interface or Ericom PowerTerm WebConnect.
"Almost like Citrix GOTOMYPC but inside an organisation"

What a world could be soon, I was with a client today and they are thinking hard about this and the future virtual
desktop and being able to migrate to vista or office 2007 or an other new application in minutes or seconds.

How cool is that. I look forward to seeing the next 18 months.
