From the acceptable use policy of Microsofts Anonymous Alcoholics^W^W academy alliance program:

  • Windows XP may not be used only as a terminal for accessing a UNIX telnet server.

Interesting. Who would still be running a telnet server? Everybody I know uses SSH. And if it’s just for telnet, there are no benefits from graphics or sound drivers that might not be available for Linux. If I’d ever use XP on “thin clients”, I’d use NX or XDMCP or VNC, but never telnet…

Also this explicitely only applies to XP, not to Vista?
