Someone wrote on this newsgroup recently that he knew that "the DSP 
couldn't play and record at the same time".  Is this true?  

I'm not asking whether the SoundPlayer (for instance) will support
playing and recording at the same time.  

Rather, is there anything about the DSP itself that would prevent recording 
a stereo 44.1KHz signal - while playing another one through the stereo outs?  
(Assuming, of course, that there's enough disk bandwidth available to read 
one sound while writing a new one.)

It seems to me that the DSP has plenty of power to handle two stereo jobs in 
realtime (eg, it can play 2x2 44.1KHz tracks via rtmix), but I dunno...
