Perhaps it can be made ever so slightly less ugly if endpoints get an
"address" that consists of a 32 bit IP address + (n) upper bits of port
number.

This might be 4 significant bits to share an IP 16 ways, or 8 significant
bits to share it 256 ways, or whatever.

And you store the 4 or 8 bits in what part of the IPv4 header, exactly?
