[LAU] q: expresscard audio I/O

[Kim Cascone]

wondering if someone can illuminate me as to the state of audio via the 
expresscard standard?
I Googled and found the Indigo card:
http://www.echoaudio.com/Products/ExpressCard/index.php
has anyone gotten this card working on Linux? issues? problems?

and does anyone know if there are new (re: cheaper) audio expresscards 
on the horizon and if this is standard is being adopted by audio 
hardware manufacturers?
I know Apple waffled on including it on MBP's...
thanks in advance
