InterNIC's current CIDR allocation practice does not support either of 
these options.

Here's an idea. Let new ISP's reserve large blocks (say /16's) in 65/8,
66/8, .... but don't let them actually use these addresses on the global 
Internet. Then, the ISP can run a Network Address Translation gateway and
give their customers 65/8 addresses while still using a chunk from their 
provider's block. And they can switch providers without forcing their 
customers to renumber. Then, after they have demonstrated that they 
should be given a /16, open up the block they were given in 65/8 for use 
without the NAT.

Of course, there is one little problem with this....

How did these guys get such big chunks of address space reserved?

  by 'these guys' you mean the air force logistics command?  the number you 
looked up is an aut num, not the network.  iana has these reserved, not air 
force.  or i've misinterpreted your question...
