I think that's fair comment.

Very true, and WIDE also has the luxury of a large team of people funded
to develop sofware such as KAME.
That said, totting up the IPv6 deployed routers in European academic
networks, there's probably a couple of hundred such routers at or within
one hop of top-level activity. I think Germany has the most, thanks to
the JOIN project, which connects over 100 customers, I believe.
There's two big (~20M euro) projects seeding IPv6 connectivity for
commercial and academic pan-european networks that will begin in the next
few months, subject to successful negotiation with the European Commission.
Of interest to Cambridge and Imperial is the likely launch of a UKERNA
backed "service" in the UK before the coming academic year.
