Sorry, just pressed some send shortcut in kmail I'd never seen before and sent 
off an incomplete message! So sorry for double posting.

Thanks for the warning, I'll be sure to get a real thorough understanding of 
Kolf before attempting the port, and will be ready to do a significant amount 
of work. Kolf as it stands has quite a few bugs (eg balls going through walls 
and ending up on top of each other and then behaving strangely in 
multi-player), so it could probably do with quite a bit of work anyway. 

But since I love the game, I think I'll really enjoy the project. And its 
lways good to have a bit of challenge. 

Thanks for the info Dmitry and Albert, and I'm sure you'll all hear from me 
soon when I get completely stuck! :)
