So, basically, each time the mac goes from wired to wireless, the
reflector sees the name, says, "hey, that name is in use over *THERE*",
and declares a conflict.

If tied to mac address, then I'd expect at most two names (one for the
wired mac, one for the wireless mac), which is also suboptimal, but
understandable.   SO I think you are saying that in addition to this
protocol problem, there is also some bug in the reflector causing all
previous names to be taken?

(I'm asking mostly so that I can make sure that mdnsext can capture this
as part of the problem statement.  BTW: who will be in Atlanta?)
