well i'm looking forward to it!
and u guys are right, u can turn those networks off but in my opinion it would just make the client cleaner to remove them.
but maybe that opinion will change if u clean up the GUI
one more thing: I don't know if u've noticed but in the latest beta of limewire there are firewall to firewall transfers supported. You might want to find a way to get that into gnucdna and possibly neonet considering that most of the users will be firewalled, (including me)
