As mentioned in my first response, see:
http://www.sixxs.net/tools/traceroute/
which is a Distributed Traceroute, allowing one to traceroute over IPv4
and IPv6 from most of the SixXS POPs, which are present in most parts of
Europe and also one in the US @ OCCAID.

or check: http://www.sixxs.net/tools/grh/
for a nice BGP looking glass (grh.sixxs.net for telnet ;)

To solve Jordi's problem I've brought him, offlist, into contact with an
ISP that is able to give him native IPv6 in Spain with a native route to
most places, so that problem should not exist anymore in a few weeks.

Yes, I am aware of this; as I mentioned, they are educational and have
some overcomplex routing policies. This seem to be the case for the
majority of NREN's unfortunately which causes bad connectivity towards
the 'commercial' prefixes, one day this will include a Google service,
who btw are also already using their own IPv6 prefix, and then it will
most likely hit these places that people need good connectivity to those
sites too...

Good part is that they do have a staff that is aware and understands
this issue, it is just good to note whenever doing a traceroute or
noticing bad connectivity that NREN's seem to have those issues...

Having them in GRH also allows one to see where it most likely goes
wrong.

Greets,
 Jeroen
