Hi W6,
wow is a really big bit time ....
Well the wi-fi is really bad, infact if you use it on the Mac is instantaneous.
And i already used the max compression and fastness i can do for wi-fi.
Usually the audio file is not bigger than 40K. Imagine a LAN sending 40K (it will be a second), but i don't know why on iPad/iPhone, so on the wi fi devices, it takes about 10 sec to send and 10 sec to receive.
I've also tested the game center as Radio, but with no luck.
I will think something to go faster...
For the earphone, i will take 1 to the apple shop and i will try to use it and learn how to use the button as the talk.
Now i understand what you mean and is a great idea!!
