I'm sure Marcel and Johannes are way ahead of us on this. :-)

I think you covered the basics, but you did leave-out the possibility
of using net-next-2.6 for bleeding-edge development of bluetooth 3.
Since both Marcel and I feed Dave's tree and Dave endeavours to
keep the history of that tree stable then this would seem like your
best bet.

In any case, I was under the impression that at least the initial
parts of the 802.11 AMP implementation could happen independently
from any bluetooth stack changes...?
