I'll have to look into that but isn't protobuf/zeromq an MK thing that 
wouldn't readily exist in LCNC? A fella sent me an interesting email:

I've heard of mb2hal but never looked into it. It exists as a component in 
LCNC. I don't see it at all in MK source. I'd have to look into what I can 
do with it but since it's an RT shouldn't it "just work" in MK?
