Great stuff! :)

Sending messages works fine with the lemul branch (contains the epoll stuff,
among others), using the -f20 ports. Are you using -f10?

I just had to disable that from the linux client side of pulse audio, in
/compat/linux/etc/pulse/client.conf and didn't touch the server side. - I
have it as a patch in the port:
(https://github.com/vassilisl/freebsd-linux_base-f20/tree/master/audio/linu=
x-f20-pulseaudio-libs)

Excellent!

If you enter the machine's name in /compat/linux/etc/mahine-id (IIRC), that
works around that problem as well - but it is a hack :)

3 is present in lemul, and 2 are being added as well.
