Ben The VPC Guy has just finished a series on building a "typer" application for Virtual Server.
Virtual Server doesn't support Clipboard integration (though Virtual PC 2005 does), and this app looks like a little nugget'o'gold if you like to take a more "hands on" approach with the server, especially during setup or at other times you can't use an RDP connection.

The program gives a good indication of how to program against Virtual Server, and all the little hosted serverlets inside.
