I shall be interested to see how it goes, especially if you can make the
resulting system stable. Also, I wonder whether you can use udev to
distinguish between 6 different copies of a nominally identical item?
Some may let you use a serial number. Using the BUS id would be cheating
- one ought to be able to plug it together randomly and have it work!
P.S. An interesting challenge would be to get separate audio channels
working (eg a 5.1 channel motherboard could give 2 1/2 stereo outputs!)
Or you could use alsa to multiplex all the users together so that
everyone can access the speakers (and trust the users to resolve conflicts).
