Uhm, excuse me, is something wrong with my calendar and we had Apr 1st
yesterday?

For example have a look at http://www.6win.de, the former IPv6 project
group of IPv6 at the german NREN. The graphs are frozen at the numbers
of Jan 6th since IPv6 is now managed by the same NOC IPv4 is, and they
don't update that page anymore. When looking at last months graphs for
their external connections C&W, Geant and DeCIX you get 3Mbps on
average, which makes 200pps already with largest packet size (average 
is more like 300 bytes). Unfortunately there is no pps-graph available,
but I believe AS680 did more than 1kpps on average alone. Another nice
stat (no pps again, but you can do the math) is at
http://www.sixxs.net/misc/traffic/ .

Sprint is far, really far away from the center of the v6 world. Among
the large international carriers doing IPv6 I'd call C&W, NTT, GBLX and
Tiscali the center. Sprint appears in a number of AS paths just because
it is the link between the "decent" IPv6 networks and the swamp space
consisting of announced but unused prefixes and networks still doing the
old 6bone way. No wonder they see no traffic. Apart from
a.gtld-servers.net I can't remember seeing interesting content behind
Sprint at any time.
