I've never thought of that but it could.  I'll mention this on the k12ltsp list
and see what response comes back.

Monty mentioned on IRC that he's working on fusd (Device files from userspace.)
 He thinks that will allow pulseaudio to create the device files rather than
having to load a library that overrides calls to /dev/dsp with calls to
pulseaudio instead.  Without that I think all prior art is to use LD_PRELOAD in
this manner.  (Although thin client is the only place I'm aware of them doing it
system-wide; most places use the {esd,arts,pa}dsp wrapper to target specific
applications.)
