I'm completely ignorant of udev-acl, but if this is the thing that
moves around device access rights when you switch users, then I agree.

If we could pass around /dev/soft_synth rights like we do the sound
card, we could make this work with user-space code.  The critical
thing is that /dev/soft_synth rights must always follow the audio card
rights.  Is it easy to make this work very reliably with CK/udev?

If this is only a kernel module change, I will sign up to do that.  It
would be great if we could leave espeakup and speechd-up mostly
untouched.
