Any chance that someone has any real-world experience as to the clock 
accuracy of the sound card used in the external interface? I.e. how far 
off is it on Rx and Tx? I think MixW in Windows lets you check that, or 
MMSSTV.

I see they also claim Linux compatibility with this product, too.

I'd be really interested to see how the clock timing stacks up on this, 
i.e. if it's reasonably accurate both in Rx and Tx sample rates and 
stable as to any error value.
