The /24s are in the routing table one way or the other.

Current policy still allows for IP based hosting for a number of things
including SSL certs (which older computers still don't support properly).
($12/cert + $6/domain)* 512 = $768/mo.  Not exactly frugal and throw in a
pair of cheap T1s ($200/mo).  So yes it is very possible to contribute very little
and still use up a routing slot.

PA vs PI division does support provider lock in.
So in that sense it is a Pony for the ISPs.
It also means that the PA customers are paying for
a lot of routers for the ISPs.

I am not sure which way to go on this proposal.
It does cost a lot per routing slot and discouraging
indiscriminant use of routing slots is a good goal.
Some TE is necessary and unavoidable.

Anyone with a sufficient business case for being multi-homed is
going to be multi-homed.  Cost is not a big barrier.
