I note that rendezvous, being a broadcast-based protocol, is chatty as

it doesn't scale, and winds up bogging down LANs... (Witness the death
of netbeui, appletalk, etc) So what is different about Rendezvous that
will keep this from happening? Anything?
Well, given that you've already determined that "being a
broadcast-based protocol, [Rendezvous] is chatty as hell", I guess
nothing...
Unless of course, your assumption is wrong, and you're just spreading
FUD. From Stuart Cheshire's slides at the O'Reilly conference

Rendezvous avoids chattiness through:
Aggressive Caching
Duplicate Suppression Section in Queries
Duplicate Answer Suppression
Duplicate Question Suppression
Exponential query backoff
Service announcement on startup
Exponential announcement backoff
