The "word on the street" is that UDP is approximately 10 times faster
than TCP, so you would have a 5 times speedup all-in-all.

Appropriate.

Sounds like java applets.

I think you will have a tough time bringing this system to real time
responsiveness, which is a critical feature of an interactive game.
Maybe it is OK for general graphical applications that don't rely on
that kind of responsiveness [I'm thinking spread sheet, graphs,
picture browsing, simple drawing program, turn-based-games etc.].

Anyway it is a good and fun toy to play with, good luck!
