f-root does this on the IPv6 side: 2001:500::/48

Whether that's available everywhere on IPv6 networks, is as Bill pointed-out, another question.

Have a look at it: http://www.sixxs.net/tools/grh/lg/?when=now&year=2007&month=05&day=29&hour=18&show=allpaths&format=html&report_grhwork=on&report_grhfail=on&report_nongrh=on&findtype=prefix&find=2001%3A500%3A%3A%2F48

Ironically, AS25689 (that's me) does peer with the local f-root via IPv6, but SIXXS claims I don't see it. :-)

It doesn't claim any such thing. The "ASNs that do have the prefix" are the ASNs that are found in the paths for the prefix, as such we can deduce that these ASNs see that prefix, otherwise they would not carry them. Then there is a list of GRH participants, these are sites we know that exist and should have it. Thirdly there is a list of ASNs that we see somewhere in the BGP tree. These latter ones are guessed to not have it as they don't provide a feed, we don't know for sure, they might and they might not. Sign up and provide a feed and you will know. Note that this all stated below the headers too ;) Greets, Jeroen
