One might think that this simple change in global policy for AS numbers should be fairly easy to implement. But as this involves one of the key elements in the BGP routing protocol it realy has some impact on all routers on the internet.
This article from the RIPE NCC website highlights this challenge:

Make sure you push your vendor to implement the latest version of the Internet Protocols.
In addition to my day job at Visma - I spend time on following the global Internet Policy process on IP addressing in ICANN and the regional processes in RIPE. I also have an interest in new technologies and open source solutions in particular. This blog however - is purely personal

New Global Policy for Autonomous System Numbers
Autonomous System Numbers are used in the routing system in the Internet.
A simple description of an AS number is a number every ISP needs to refere to its own routes in the global routing table.
As not only ISPs needs AS numbers but every network with a separate routing policy, the original 2 byte AS nubers were not enough and the routing protocols has been updated to allow for 4 byte numbers.
The new global policy describes how ICANN/IANA will allocate blocks of 2 byte and 4 byte AS Numbers to the RIRs.
The ICANN board ratified this policy on July 31 2008: http://www.icann.org/en/topics/policy/update-aug08.htm#15
