I wanted to mention that 2 other servers run on 5353, according to a
march email (for a current total, to my knowledge, of 3 servers)
and those same iptables rules work on a rooted android smartphone with
iptables support.

Also, I think I can get a set of ipfw rules for apple and *bsd
systems, however, I cannot test it on a mac personally, I'll be on the
latest FreeBSD.
Still unsure of how to apply this to Windows, all I can say is stay tuned.

Slightly Unrelated note, Things are starting to work in my favor
again, with this I should have a server running shortly, listening on
53 & 5353, and I'll be working towards another method for this,
primarily for those lacking administrative rights to use this method,
or windows (at least until I can get a smoother solution for windows)
Glad to be able to help OpenNIC again.
