32-bit AS numbers

Hi all, As you (hopefully) know, as of 1-1-2010, the RIRs will only be giving out 32-bit AS numbers. I'm writing an article for Ars Technica about this, and I was wondering about the perspective of network operators who may be faced with customers with a 32-bit AS number in the near future, and how the vendor support for 32-bit AS numbers is working out. If you send me info in private mail, let me know your title/ affiliation and whether I can quote you or not. Iljitsch
