Sorry for the late response (I'm in ELC).

Yes, use the client sample (which is part of the submitted patch set)
and not the omx/server samples (which are public, but were never
submitted nor cleaned up).

The channels are created dynamically: the rpmsg bus designates address
53 for a name service, which listens to channel creation/removal
announcements coming from the remote processor. Take a look in
virtio_rpmsg_bus.c and you'll immediately see it.

Hope this helps,
Ohad.
