Good point.

There is some danger here. As of today, there can be
only 8K TLAs and there are more ASNs allocated
already. I fear a rush to get a TLA "just in case"
by people that don't really need one. To be honest,
it has crossed my mind. With several thousand modems
and multiple DS3s OC48s I would probably qualify for
it. With such scarce numbers, it might even be a
sound business decision. If I could get an IPv4
class A today for a few thousand dollars, I certainly
would. Just in case.

There needs to be some mutual awareness between all
the different solutions. As of today, there are still
people that say that we should design a mach 4 Yugo...
