So with two entire PCs at my disposal, I left them idle and skyped with JVM for almost 2 hours on my lowly little s620 mobile phone, which I also used to send a picture of myself to him via email from the phone during the call.
Worked well over 802.11g although there are a couple of limitations:
1. The phone can only be used in speakerphone or wired headset mode. Skype hasn't sorted the bluetooth or regular audio paths yet.
2. His inbound audio stream would sometimes repeat certain words and phrases repeat words and phrases (just like that). It didn't jitter or stutter, just repeated whole 2 or 3 second chunks. JVM didn't hear anything like that on his end.
3. Sucked my battery dry in 1 hour. The phone had 2 bars of juice when I started but it ran down quite rapidly when I had the speakerphone on.
However kudos to Rogers wireless, for although they are the Great Evil, they are one of the few North American operators to ship a GSM/EDGE phone direct from their retail stores with wifi enabled.
Thumbs up for the little s620.
