VoIP+IAX Program Theory for OM

I too run my own asterisk server.  I'd think IAX support on an OM client 
would be critical (at least untill were all on ipv6).  The only reason 
you'd run a voip client on OM is so you can roam from voip to GSM with a 
preference to VOIP when wifi is available so supporting IAX would make 
this as painful as possible.

Excellent idea!  I'd be happy to help with anything other than coding 
once I get a freerunner.
