LPC: Linux audio: it's a mess

the point is that aoss (and other variants) can't catch *everything* (mmap, etc), but I believe CUSE is intended to allow a user space process to catch all the same stuff as the kernel mode emulation can.

also, aoss is a pain for most users, because they have to start the program they want to 'emulate' under aoss, typically from a command line. CUSE just sits there as a daemon, waiting for any process to attempt to use /dev/dsp.
