Don't tell Verizon, but we're using Skype on some laptops through Verizon's
aircards on EVDO with great results.

As to the data-audio audio-data conversions, that doesn't take much of a
modern PCs CPU capacity. Look at how easily you can play a 328Kbps MP3
with Winamp in full stereo. It hardly bothers the processor's free time to
do other things. I suppose it depends on how complex the encryption scheme
is once the data conversion has been done. I talk on Skype on my Athelon
desktop through a USB headset at the same time I'm watching a DivX movie
with VLC and downloading from Usenet more movies and nothing balks. That
wouldn't have been true 5 years ago on Win98SE...(c;
