I can describe Sun's implementation.

If the size of the /etc/rmtab is a burden then it's OK just to
truncate it.

No. I think you just want to be able to delete entries selectively
from /etc/rmtab.  How about:

	grep -v "<client>:" > /tmp/rmtab ; mv /tmp/rmtab /etc/mtab

No.  The /etc/rmtab entries are the only "state" that a server
maintains concerning individual clients.
