With the launch of Vidyo.TV i decided to try out some more live mobile webcasting and used ComVu as my test. I added the broadcast to Vidyo and started the broadcast around 10 minutes ago. It picked up maybe half of what i said (so kinda like my Son then!) and dropped some other parts. It seems to lose data quite often - probably as i'm over GPRS, but then so will most people so it's a reasonable test.
Still, at this point it's better than the alternative (nothing) so it's quite neat to play around with. PC webcasting will still be ahead of the mobile equivalent for a while i think.
