As has been pointed out, the next-gen XO wireless FW does not have mesh 
support; however, there are still plenty of end users and developers on 
the existing XO-1 laptops and I don't think completely removing mesh 
support is an option our community would be happy with. However, I also 
don't want to end up with a libertas fork (all our mesh patches are
currently upstream and not forkd off) in the OLPC tree so let's figure 
out a path to make this work for everyone.

It looks like there is already some work in progress towards mesh support
using cfg80211 [1] and if I can get pointers to the latest version, I can 
point the OLPC community to them and see if we can find some testers.

Or a few XO-1 laptops? :)
