Icecast - Aug 2006 - using mulitple sound card inputs

I've been able to successfully stream using Icecast with Darkice on my
Debian box.  I want to be able to stream multiple live streams from the
same box using different sound cards (Basically, we have groups that
will be using different TV channels and want to be able to stream the
audio to the user's pc's for the proper channels they are viewing).  Has
anyone tried to do this?  

Thanks,

Andrew

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.

Pure speculation: I wonder if it would now be more economical to use a 
multi-channel sound card, something like a Delta-1010? Perhaps you could 
fit several of these cards to a single host?
