One thing, I know we can test the audio with something like Skype, and
indeed the first one will probably use Skype or something similar to handle
the audio path, but fielding this with Skype may present some issues as
some countries are blocking VoIP because it hits their cash cow telco
operations. So I need to come up with something that I can run on the
two ends that will work similar to skype but not attract the attention that
skype has, i.e. be able to change the port number used to carry the VoIP
is probably the fix.
