Contrary to someones believes I don't think AF_INET is that fast (e.g.

Oh you mention a recent zork it seems ;)

Are we speaking of performance problems, apart from scheduler problems
for D-Bus (each message wakeing all receivers, all receivers read and
drop message but the target) ?

I am actually one of the few people working to improve performance on
both AF_INET and AF_UNIX parts. Just take a look at recent commits.

Right now you can send/receive millions of udp messages per second on
your linux machine, if you figured out how to avoid process scheduler
costs. If D-Bus wants more, I highly suggest using shared memory
instead of passing messages.
