I was annoyed enough with the problem to want to share it...

A machine on net A can bind to ypserv on net B if the client's broadcast
address is changed to that of net B. It can then be left or put back,
although if put back to the A-cast the binding may get marked bad if the
ypbind can't communicate with the ypserv (just write a daemon that checks
the binding every few minutes and swaps the broadcast addr for a while if
the binding's bad).

In our case we just leave the broadcast set to B-cast since the machine is
an effective net-B peer except for net-membership.
