Quite probably. However, if we're waiting for an implementation before we give our requirements for the protocol that was implemented, we should prepare to be disappointed. ("Yossarian!")
A small-to-medium, multi-homed, tier-n ISP can get PI space from their RIR, and don't need to worry about shim6 at all. Ditto larger ISPs, up to and including the largest.

Actually, this part is most definitely non-fiction. According to the harmonised IPv6 management policy in effect across all the RIRs, anybody who can demonstrate an even vaguely plausible plan to connect 200 IPv6 customers within two years qualifies for a / 32 PI allocation. I've assisted many small, tier-N ISPs to do just this (including hosting companies, for whom the connected customers were colocated customer servers). Joe
