pd will happily use several devices, its been talked about at length on 
the list (search the archives if you need more info) ... the only 
drawback is that different cards do not sync with each other and they 
can empty their buffers at slightly different rates, so sometimes you 
get clicks because one of the cards buffers has run empty.  not 
recommended for hifi situation.  why not get a multichannel card like 
the Midiman USB Quattro?  I just bought one and am loving it.
