It has been written down many times that p2p messaging on mobile devices does not really work (in Skype's case, the original p2p architecture used online devices as temporary supernodes, draining their battery, increasing their data usage).

I was under the belief that it looked for nodes with things like high bandwidth, low latency and no problems with firewalls and such. And even then, it's not like they didn't have a clump of machines 'always on' as supernodes anyway.

Because of all of that, I find it hard to believe that Skype would choose mobile devices as supernodes...
