My impression (which may be wrong) is that with respect to (1), a) most folks can't justify a PI request to the RIR, b) most folks don't want to deal with the RIR administrative hassle, c) most ISPs would prefer to not have to replace their routers. That would seem to leave (3). Am I missing an option?I don't think so, though I'd add 2 bits to your 1 and 3 options: 1) we ought to make getting PI easy, easy enough that the other options just don't make sense.Surely your not saying "we ought to make getting PI easy, easy enough that the other options just don't make sense" so that all residential users get PI so that if their ISP disappears their network doesn't break?
all the world is not a corner case... I don't think sane folks are supportive of 'every end site gets pi', I think it's somewhat sane to believe that enterprise type folks can/should be able to get PI space to suit their needs. ULA for enterprises is really not a good solution. Cable/dsl end users can certainly apply for PI space they may even be able to justify an allocation (see owen...) I don't think they'll have much success actually getting a DSL/Cable provider to actually hold the route for them though... so I'm not sure that your pathological case matters here. -chris
