Tunneling does *NOT* improve connectivity.

Also note that these /48's are not visible at some ISP's:

grh.sixxs.net> show bgp 2001:503:a83e::2:30
BGP routing table entry for 2001:503:a83e::/48
Paths: (38 available, best #35, table Default-IP-Routing-Table)

grh.sixxs.net> show bgp 2001:503:231d::2:30
BGP routing table entry for 2001:503:231d::/48
Paths: (38 available, best #31, table Default-IP-Routing-Table)

Out of the current 47 active neighbours on GRH.
See http://www.sixxs.net/tools/grh/ for more information.

For the people not seeing these ARIN micro allocations, update your
filters (see: http://www.space.net/~gert/RIPE/ipv6-filters.html), or if
you have no intention of maintaining them, set them to filter anything
>/48 or just simply remove them as that is less of a pain and breaks
less things. 

See below for a traceroute from my home DSL line to B, as can be seen
the biggest latency is apparently between gblx and the US part of gblx,
I'll contact them to inquire what is going wrong there as ~150ms is
twice the atlantic, the rest of the path seems fine (20ms difference),
though there is an asynchronous route back in the path.

Greets,
 Jeroen
