Hi James,

What's it worth to you? Literally, whats the maximum amount of money you're
willing to spend on an AS number recovery effort before you figure, "meh,
it's not worth it?"

And before you come back with "Well they may be using it internally where
> it doesn't need to be in the GRT" - that's why we have Private AS numbers.

Private AS numbers suffer from the same interconnection collision issues as
private IP addresses and if you have a private AS it's *because* you're
interconnecting networks.
