Alternative to Create a new wireless network

I thought the reason we have this change at the moment is that we have
tracked the change done by Sugar development upstream, between 0.82 and
0.84 ... and we have chosen not to merge the XO-1 specific changes we
did for 0.82.

Today during a simulated training and assessment (for my training
certification), I used four XO-1's with build 802, and after being
powered up they automatically became aware of each other through their
mesh network.  I don't see this happening at the moment with XO-1.5 with
build os54.  Are you, Reuben, also concerned at that loss?  We should
probably put something about that in release notes.

OpenFirmware has a method to detect channel use and avoid it, and it is
used in the NANDblaster feature on XO-1.  Avoiding overlaps and
interference is not difficult to code, but it is unlikely to work as
well as getting a human to make the decision.  Decisions made by humans
deliver a cognitive bias in favour of the decision.

Agreed.  Apart from those problems I've found no current issues creating
and operating ad-hoc networks on XO-1.5.  Sharing activities is a
different matter; #9669.

But I'd also like to see the previous UI restored, even though it won't
map to XO-1 semantics, nor even interoperate with the XO-1 network.
