Yup! I've gotten 7 feeds from a single host. I had 11 PCI sound cards in 
the machine (FreeBSD w/ Darkice feeding Icecast). After 7 though, it got a 
bit shaky.

I used a Creative Labs sound card that I specifically hunted down that did 
not feature the MIDI port (The game port).

Photos of the host (I built two of them, each with 6 inputs):

In this day and age, I would look at the Creative Labs USB sound devices. 
There is an older one that can be had for $15-20 each. The thing I'm not 
sure is upon system reboot, with those devices connected to USB hubs, will 
they order themselves the same? This is important or else audio inputs 
will end up on the wrong mountpoints.
