At Cambridge my colleagues have an experimental DNS-SD setup for printing
from eduroam. Rather than the reverse DNS option, we're using the forward
option where clients get the domain from DHCP, so I just needed to add a
few records to the DNS and try not to worry too much about how competent
the print server is at DNS. The forward option greatly simplifies wireless
subnet allocation, and is conveniently v4/v6 agnostic.
