Oh, yes. There are several:
Userspace Realtime
halscope scope_rt
halsampler sampler
halstreamer streamer
and of course emc's task (userspace) and motion (rt) communicate through
such a shared memory area.
halstreamer is probably the most similar to what I'm suggesting, because
a userspace process loads data and a realtime process consumes it.
