i dont know if something like this is possible for pgp/gpg but there is
a project for ssh public keys to be distributed via DNS bind 9 but it
may be a similar project ( http://www.cs.jhu.edu/~smang/sshproject.html
)

there are a couple of programs out there that may be helpful, hping (
http://www.hping.org/ ) is one that gives you the ability to ping and
traceroute based on port and protocol. You know nmap as the other one,
but i think there should be a way to limit the port and speed of scans
to more acceptable levels.
