While I think the address planning problem is serious and hinges
directly on this issue, I believe all these opinions and stances have

I do not know about arin but ripe changed it's policy so you only have

Marco Hogewoning of Dutch ISP XS4ALL talks about the roll out of IPv6
in their 300,000 customer network. German modem vendor AVM supplies
them with a CPE that supports native IPv6, although it does have some
limitations that need to be ironed out.

Obviously using 40 gig waves as the foundation blocks of one's network provides
some economies of scale and per unit capex cost savings.
I would be curious if anyone knows how to convert this SONET/SDH 40 gig waves
into a 40 gig Ethernet handoff?
