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.

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).
