So what's the user to do with this single address, and his network behind
his router?  User IPv6 NAT/Masquerading?

I strongly encourage you to re-think this approach.

The whole point of IPv6 is to have plenty of addresses - and as there are
4 billion /32s, using one to give your users at least a /64 is the *right*
way to waste addresses.  Do not encourage anyone to use NAT66.

Yes, we're aware of that, but this is the old "a user only needs
to have a single IP address, and can use NAT" world.

Since we do not want to encourage this model for IPv6, nobody has ever 
brought forward a proposal to allow this approach for IPv6 PI.

(Now, I have no good answer what the Freifunk community *should* do.  I can
understand that you're indeed set up quite differently than a traditional
ISP - OTOH, you're not the only one who runs a network on a non-commercial
basis and needs IPv6 addresses.  So using PA space from a friendly ISP in
the neighbourhood - like, a /40 or even a /32 - might be a workable 
solution...  yes, renumbering will be nearly impossible, but right now
the RIPE model doesn't really permit free rides "I want my own addreses, 
I want to run something that is similar to an ISP business, I want a slot
in the global routing system, but I am not going to pay for it".  We might 
want to change our member structure to accomodate non-commercial LIRs - but 
that's a topic for the AGM to decide...)

have you enabled IPv6 on something today...?
