I cannot agree with that. As I wrote I hope that we will try as much
as we can to connect everything in one big mesh and not have
individual "bubbles". What you write could be true only in
mobile-phone only mesh networks. But even there this is not true. IPv6
can be tunneled over UMTS/Edge/CDMA, 6to4 could probably also work,
not to mention that even my Android phone now has support for ethernet
over USB, so that I can just connect it to my laptop and it can give
uplink to the mesh (if we talk about mobile-only meshes).

But of course we will not have such meshes. I hope. There will be
laptops and "big" nodes we already have, which will allow for
uplink/gateway. And they will be also powerful enough to run AHCP
daemons.

So using AHCP (or similar technology) on any gateway which happens to
be in mesh is way to go. And using IPv6. Then if the mesh does not
have gateway, we have only MAC based IPv6 addresses. But if it has,
then we get public IPv6 (or even multiple public IPV6 from every
gateway one; this is even recommended approach for multi-homing for
IPv6 in RFC, as far as I am aware).

And even more important: power consumption. Currently running OLSR on
my Android phone depletes its battery in four hours. This then makes
it something which I cannot have on all the time. But it would be
great if I could have.
