There's a *certain* amount of sense in having the basic DBus transport
and security handled in the kernel.
I've certainly seen people *avoiding* DBus and re-inventing the wheel
for themselves because of the overhead of having to bounce everything
through the dbus-daemon in order to handle routing/security/etc.
Perhaps we wouldn't eliminate dbus-daemon entirely, but at least if
messages could get from one dbus client to another *without* bouncing
from user -> kernel -> user (dbus-daemon) -> kernel -> user, that would
Think of it like kernel-side NFS, perhaps. The fast path in the kernel,
and the rest can live outside.
Didn't Marcel have an implementation of this at one point?
