Thanks for bringing up your concerns. If you think of further things,
you should also know that you can participate remotely to UDS:

That way, if the schedule suits you, you can react in real time to the

I think this ties in to what Jan was writing previously -- some
mirrors are ready, but not all of them.

Yup, this will work in Natty; we ship ISC-DHCP 4 which comes with IPv6
support in dhclient.

AFAICT it's not yet supported (either in PPPoE itself or the work
hasn't been done in NM yet; see

I'd like to do it; I haven't really thought of it as a goal though, in
Natty it was mostly a "if I can take time to implement it". Since I
guess it's probably not too complicated to implement, I'll put this in
as a tentative work item for the IPv6 blueprint.

That's something else that should be kept in mind for the dicussion at
UDS, so I'll add it to the blueprint for discussion and review (in
case it already works).
