This absolutely doesn't work. And DNS SRV RRs have roughly zero uptake 
for stuff that matters (web, email).

Oh and we need to work around the whole IP reputation system that 
governs email today.

Is there even any IETF work being done on getting port forwards on a 
device behind your immediate LAN at home?

Do you have any more practical proposals, or..?
