The filtering access part of this daemon is also not mapping well onto

already, and intend adding role based access control to further filter
things, integrating with the existing apparmour/selinux security
models.
A qemud that filters based on UID only, gives users a side-channel

That's true. Any time you write a multiplexer these issues crop up.
Much better to stay in single process land where everything is
already taken care of.
What does a multiplexer give you that making individual qemu instances
discoverable doesn't give you? The later doesn't suffer from these
problems.
You don't get a directory filled with a zillion socket files pointing at
dead guests. Agree that's a poor return on investment.
Maybe we want a O_UNLINK_ON_CLOSE for unix domain sockets - but no,
that's not implementable.
