You could try Windows 2008 R2 application server VMs (one per
application) with thin clients. Supposedly the live motion video is
much better in 2008 R2 and RDP6.1 then in prior versions and with the
ability to serve applications instead of whole log in sessions this
gives as much resources to the application as possible. Go for an ESX
server with 2x 6 core CPUs and 32GB memory. It will cost double then
what you priced out already though.
