I don't see a problem in adding a BeOS client. What client/peer_id(s)?
I doubt you left because of BitComet drama ^^ religious wars, although entertaining, aren't very practical.
Although you may be computer savvy enough to distinguish between Shareaza and libtorrent, in fact most people aren't. The whitelist should help these people.
Most people I talked to that were using BitComet got it 'from a friend' and most were more than happy to switch to Azureus or uTorrent. We can't please everyone.
