Client-Server coding in c#, need an idea

[davidc538]

I have an assignment for school this semester where we have to develop a client server application in c#. I'm a pretty confident coder but I have no idea what to do that would knock the teacher and the rest of the class off there feet.

any ideas?

thanks in advance

how large a project should it be?

You can think of
-games (using xna? or text-based multiplayer)
-dataserver (sql-like apps)
-remote controlling (control your pc from another pc using c#) <- would be my bet
-same as above only just for a media streamer or something
-backup system (client backs up data to server)
...

probably a lot more, but these are the first ones that come to my mind
