The current PI policy does allow for variable sized assignments based
upon need for more than 65536 subnets.  There have been two such
assignments made so far.   I'm sure if you submit an application
that reasonably justifies your request you can get the subnets
you need, as that was the intent of the policy.

We do need to make that policy more specific as to what "justify"
means so if you have any suggestions we would love to hear them.
