OK, my last mail was maybe a bit terse.  Some background might help.

We (KPNQwest, formerly EUnet) are a "supernational" registry.  In the IPv4
world this is much like having 6 individual large registries with the
corresponding number of open allocations that implies.

Now, in the IPv6 world I'm told that we can't get an IPv6 sTLA for our direct
backbone customers or for any of our other national networks because KPNQwest
Finland (covered by the eu.eunet supernational registry) already has our one
sub-TLA.

Of course, that one sub-TLA gives us a total amount of address space which is
adequate for our current requirements for the whole network but once this is
split over each of about 20 separate autonomous systems, each with their own
routing policy, this is hardly going to result in optimally aggregatable
routing...
