Yes, I already offered to start a poll. A poll that pointing out non-commerical usage is free and license fee is $100 can be started.

Non-commerical usage is already free.And if someone wants to go commerical, $100 should not be problem.(id rather paying $100 for raknet instead of going commerical with dplay.)

and lobby system,auto patcher,security,Voice communication, far better MMO capability than play. I could pay more than $100(you know, you pick the price) for such robust library if i ever do something commerical.

check the class/function list on the raknet manual, such funcs. exist:
RakNet::ClanJoinInvitationAccepted_Notification

nearly everything needed for a mp game.
