Is it feasible to run HSMM-mesh stack on an Android phone? I'm guessing OLSRd was ported for Android already so that should be feasible (http://www.olsr.org/?q=olsr_on_android).

So Has anyone did that?

The idea is to run a SIP phone app on the phone to make peer-to-peer calls (using DNS names of nodes or their static IPs) - thus no dedicated PBX is required. New android phones can be purchased for less than $100 (and used even cheaper) so it would do an ultimate walkie-talkie on steroids.

I know it runs on Raspberry Pi: https://github.com/urlgrey/hsmm-pi but a phone already has mic/speaker, screen, keyboard so is more convenient.
