Hmm I am thinking that my understanding of the ad-hoc implementation
might be incorrect.

I was under the assumption that one XO acts as the ad-hoc host, and
the others connect to it. That made me wonder whether that host could
limit how many clients connect to it.

What I gather from what you're saying is that there's more of a
peer-to-peer connection happening, similar to the old mesh on the
XO-1s. Or am I confusing my network layers?
