I've used the m-audio Delta 1010LT card, which has 10 inputs (and
separate input for each channel). The ALSA drivers under Linux support
this card quite well. I'm sure there are other cards like this one.

You could use darkice to encode each of the inputs, and send them to an
icecast server.

yes, actually it is, but it will take up 4 of your PCI slots.
alternatively, you could try to use 4 USB sound devices - also supported
by ALSA drivers under Linux.

IMHO you're better off with a single, multi-channel sound card though.
