RE: 4 Byte AS tested

One test case I would like to see is alternating 2- and 4-byte ASNs in the path. This may be harder. E.g., AS_PATH = 1239 23456 1221 23456 23456 23456. Or how about an AS_PATH including the 4-byte ASN placeholder (23456) whose origin is a 2-byte OLD speaker? E.g., AS_PATH = 1239 23456 1221 23456 23456 23456 12234.
I've done a number of small scale permutations with BGP configurations, but larger tests of the form you describe here will need some more willing participants, particularly if we are interested in doing this in the context of the Internet itself rather than in a collection of small scale ebgp peerings.
