Right, this would be the reason to do the new backplane-- just to have more
slots available for all the sound card variations. You could use two of
the "6 slot" backplanes and connect them together (resulting in a 10 slot
unit).

This is a really slow bus, so two layers would be fine. If you go with a
metal cage I doubt it would even need any layers for EMI. (Not like anyone
is going to take it through FCC part 15 anyway...)
