Interesting. Balkanization of the Internet anyone? As one other commenter hinted at, it does sound like a recipe for encouraging multi-homing, even at the lowest levels. How many ASN's can the system handle currently?It's a 16-bit number; 0 isn't used, and the IANA (per RFC 1930) reserves 64512 through 65535 for private use. So from a resource allocation perspective, the answer is 64511.
There is a proposal to introduce 32-bit AS numbers. See, for example:
We have talks scheduled for Los Angeles about AS number exhaustion.
