Out of interest, is there a report that details the number of unused older AS's in the Internet and what is being done to recover them to recycle, as we approach the 53k mark and the 32 bit numbering scheme, it strikes me that we probably have a lot of stagnant AS's out there due to takeovers etc..
Any thoughts?

It's a bit dated now, but the RIPE report, ASN MIA, sounds like what you're looking for... www.apnic.net/meetings/21/docs/sigs/routing/routing-pres-uijterwaal-asn-mia.ppt
When I look at this more recently, the conclusion still seems to be valid: we'll run out of 16 bit ASN's somewhere in 2011 to 2013. There are a lot of unused ASN's out there. Recovering them will postpone the problem by a few years but it won't solve it. The basic problem with recovery is how to decide if an ASN is really no longer used/needed. There is (still) no mechanism to do this.
