Don't forget ecasound (w/ ALSA):
ecasound -a:mon -i drums.wav -o alsa,default \
-a:rec1,rec2 -f:16,2,44100 -i alsa,default \
-a:rec1 -f:16,1,44100 -o first_rec_channel.wav \
-a:rec2 -erc:2,1 -f:16,1,44100 -o second_rec_channel.wav
... with OSS you just replace 'alsa,default' with '/dev/dep' and it'll
work (assuming your OSS drivers support full-duplex).
... with JACK it's even easier:
ecasound -a:mon -f:16,1,44100 -i drums.wav -o jack \
-a:rec1 -i jack -o first_rec_channel.wav \
-a:rec2 -i jack -o second_rec_channel.wav
... you'll have to use qjackconnect or jack_connect to connect the port to
the soundcard ports.

And ecasound *is* trivial to set up. :)
