...are there any sound cards that can read more than one stream at a time, ie: One copy of mp1e can open /dev/dsp0 for the CD input, another copy can open /dev/dsp1 and record the line input, etc, etc? Even if they were in mono....

You *might* be able to split the left and right channels into
two mono "devices" with a little .asoundrc magic, but I don't
know how. .asoundrc is not the most thoroughly documented
thing in the world :-] ... there are some examples of
using two cards as one in the ALSA wiki, but I don't know about the
reverse. See alsa.opensrc.org (seems to be down at the moment).

I had a look at what you see. Looks powerful, but I guess it depends on the ability of the card itself to be able to split channel control as well... Hmmm...

Any asoundrc wizards looking on? ;>

If it has USB, you could try attaching a couple of cheap USB
sound devices to it, e.g. the iMic.  I don't know how
many of these you can use at once...

  That might be the winning answer, thanks.

Another option would be something like a used Delta 44,
which would give you 4 analog inputs; with the aforementioned
asoundrc magic, you could conceivably use it as 2 stereo
devices or 4 mono devices.

There would be some curious looks around here if I started ebay'ing audiophile cards with the company credit card. There are a few home studio guys around here including me, I have an M-Audio 2496 in this box here. ;>

The delta would probably work, but those 1/4 inch jack breakout boxes would require a lot of messy wiring conversions. :<
