IEEE chose to make wi-fi networks look like 802.11 LANs, similar to
ethernet. It might have been a bad idea in retrospect, but now we
have to live with it.
AFAIK, the bulk of the problem with multicasts over 802.11s (and not
all wi-fi networks) is that those must be propagated at the slowest
possible link speed in order to reach all nodes.

Ok, but how would the laptops advertise their SRV records without
Wait, are you perhaps suggesting to use DDNS to publish those services
on a nameserver running on the XS?
