You know what would be freaking awesome? If there was some way to use the Stream link hardware, as a additional Workstation terminal for NT-based OSes. Basically, like a bunch of Thin Clients for Windows, which is what it basically is, to allow access to Windows Desktop accounts, all on one box. Would make for a nice, lower-maintenance solution, for places like Internet Cafes and Libraries.
They should really look into that. (NV and AMD do make "special" video cards, that have multi-way hardware GPU virtualization support, that could be used with an array of Steam links to do just this, I think.)
