NetworkManager and OLPC mesh update

[Daniel Drake]

I've recently been working on reimplementing mesh support in
NetworkManager and sugar.

I've written all the code and submitted all the NetworkManager patches
for their development branch, but unfortunately it looks like I won't
have time to follow up on the upstream review, backport and submit to
NetworkManager-0.7, or submit and tune my sugar patches.

I have written up the current situation here if anyone (pretty please)
would like to finish the job.
