The code that is there is there and you're welcome to start hacking,
but you'd be the first user - there aren't examples already in the
tree, which is a sign that this won't (yet) be that easy.

Certainly not - and probably the rest of the code isn't.  I'm not sure
what you're really getting at.  Most of GNU Radio seems to run pretty
reliably, but your using 'proof' makes me wonder about your
requirements.

You may, but you will surely have to dig in and really understand
what's going on, and supply some missing pieces.

Yes, but be warned that this is likely considerable work.

Sorry if I'm sounding like I'm just telling you that you need to read
and understand all the code that's already present, and that sure you
can do all of it but it's a lot of work, but that's how I see it.
Contributions of code are always welcome (FSF assignment required as
for all GNU projects).

Perhaps Eric can give a status report on what's done and what's left
to be done for m-blocks.
