Cool. So if you use private ports, you'll be totally protected from the
Internet nasties (and the Internet protected from your broken or malicious
traffic) in the same way RFC1918 addressing does the exact same thing now
at the network layer.

I'm sure everyone will filter private ports just as effectively as RFC1918
and martian addresses are filtered at borders now.

Can't wait to read the draft and RFC. Rock on.
