I believe so.  I know for a fact that it works on simple direct wired
ethernet, as you say, because Michael Stone has tested it.

There is a complete abstraction barrier between the presence
service+collaboration, and the link-layer protocol.  It makes no
difference whether it is mesh, ad-hoc, wired, or wireless, as long as
everyone is on the same subnet so that zeroconf/bonjour/avahi works.

This is a misunderstanding.  He was merely trying to clarify that he was
discussing legacy hardware with no 802.11s components.
