I see; that's very enlightening.  Then it'd really be best if libgaim  
didn't have a separate Bonjour prpl but instead had an extension to  
the Jabber prpl which allowed Bonjour to happen.

The next design question would be how it could properly use the Apple  
mDNS stack.  I envision a set of UI callbacks for all mDNS operations  
which the UI would then implement as it chose.  Gaim would use Howl,  
or whatever library, and make the appropriate calls; we'd use the  
Apple calls.  This is a larger undertaking than modernizing libezv,  
but the payoff -- full Jabber support over Bonjour, and also improved  
support for Gaim and any other libgaim-using client -- is greater, as  
well.

Looking forward, one nicety of this approach would be that when Sean  
gets libjingle integrated into Jabber for Google Talk voice support  
after Gaim 2.0.0 is out, Talk over Bonjour would be gained for free,  
I believe :)
