I totally agree with Remco except this point. I know a large european
telco that already has bought ~ 2 million IPs so they would be able to
justify the need for a very large chunk. And, besides that the
"justified need" was never something objective, it was easy to
manipulate. We should just say goodbye to needs period and stick with
one bread each so there's enough for everyone.
I think I was very specific in saying it is a bad idea for a whole bunch of other reasons, but if you want to touch 'additional allocations for LIRs' at all, it would be the one somewhat feasible option.
Which is all the more reason why any proposal to this end is a bad idea.

Remco
