Alex - your man in the middle reminds me more of Blair's Demon Eyes.
As for the gamespy logo they are showing the registered trademark symbol and yet I can't find that one registered here:

There is a gamespy arcade registered but not gamespy with the green guy.
The rules are you can display TM without having to register that trademark but you can only use the ® symbol if registered.
BTW take a look at Phorm and Webwise applications on the IPO site...
