I've tried to highlight the key issues for ISPs in an article I wrote  
in early
2007 (http://www.potaroo.net/ispcol/2007-01/asn32.html) that has a  
checklist
of things to watch out for when two or more of your peers and customers
appear on your BGP system representing themselves as AS23456.

I suspect that this proliferation of AS23456 is a _far_ more insidious  
problem
than the number format when looking at the provisioning and operational
support systems, but this is a comment based on my own extended  
experience
in developing such OSS tools for previous employers and YMMV.
