Well, how many AS numbers would you like to give out? 30000 in 20 
years? 100k a year? A million in a month? 32 bits will then give you 
2863 millennia, 429 centuries or 357 years, respectively.

This AS is only visible to around 20 peers.  :-)  Apparently you're one 
of them although I have no idea which one. The other peculiarities are 
to avoid taking up space in the global routing table, which would be 
more work but provide no benefits.
