I think the trick will be getting consolekit to assign the relevant ACLs 
to the sound card devices for each user. If this is done at the low 
level, pulse should "just work"(tm) as although it will try to enumerate 
both devices, it will not have access to one of them and thus will 
ignore it.

I appreciate this is not a "here's how to do it" but hopefully it's 
pointing you in the right direction.
