FWIW, I have implemented a message passing feature for gnuradio. Its not
part of the mainline code though. The idea is that you use the existing
hierarchical connection framework and scheduler threads to pass
non-streaming oriented data between processing units.
Since grextras requires certain patches against gnuradio, to build the
message passing blocks, you may find it easiest to just install my next
branch: http://gnuradio.org/cgit/jblum.git/log/?h=next git clone git://gnuradio.org/jblum.git
