Transport-level protocols in user space

> I'm not sure that's really true, so much in society depends on people doing the right thing even when an authority isn't watching, civilization seems to still exist. The network is just another facet of human interaction.

The problem here is that the people feeling the pain are not the people inflicting it. Even within a household. And as soon as the choke-point moves "out there", all the evidence says that people are indifferent (at best!) to the pain they inflict on other people - if it's some impersonal "them", it's not seen as important.

I think the fairest thing to do is choke traffic by IP address. And if it's IPv6, you choke based on the network portion (iiuc, v6 comes as a network half and device half, and it's allocated by the network half). That way, cheating by opening multiple connections won't work :-)
