"Running out of IPv6" (Re: ARIN IP6 policy for those with legacyIP4 Space)

What I would need if I were to go with IP6 would be to have a parallel address for every one of
my current addresses. Right now we have 2 - legacy /24's and one legacy /23 - thats it.

I'd just need the "equivalent"  IP6 space. 

We could just get that from our current provider (Steadfast in this case), but it would not
be portable and with our root servers,  (INS - please, not interested in discussing the merits 
of ICANN vs Inclusive Namespace), we would need portable IPs that wouldn't change.

ARIN does provide microallocations, but ICANN forced them to put "for ICANN approved
root service only" into their policy for microallocations, so that leaves us out.
