So far everyone who has contacted me has generally reported a positive 
experience with their transitions.

The biggest complaints so far have come from end users who want to 
multihome and will be unable to do so under IPv6 due to allocation 

End user sites seem to be of the opinion that they have enough addresses 
and that IP shortages are the ISP's problem. They don't want to spend 
money on upgrades only to wind up with a lesser service than they already 
have- and that's a fair criticism.

Does it make sense to allow early adopters to multi-home and "punish" 
those who delay by making it significantly harder? Would that help? Hurt? 
Accomplish nothing?

Regarding the prefix filters-
Do /32 filters make sense given the ISP allocation of /32 or would a /34 
filter (for example) make sense to allow for very limited deaggregation 
(to make moves and transitions easier- or to allow better traffic 
balances)- or is this just asking for problems? I'm just curious about 
opinions and by no means trying to start a flame war.
