Here in europe (RIPE instead of ARIN), you can request PI space, without
any guaranties of it being routeable, but it usually is.

Actually I've helped quite a few such customers, my recommendation
usually is to get PI space from RIPE, and get both providers to announce
it from their ASN, this works quite well, and also save a ASN - if the
customer really want to run BGP, we have arrangements with other ISP's
here, that we find a private ASN (that none of us use currently), and
assign this ASN to the customer, and we then strip the private ASN on
the edges of our network.

Naturally there is room for everybody, but things still need to work.
