I like the concept.  What exactly does "opencomm" mean or what is it
short for?  Without any background it seems like a really unintuitive
name.

Do you have a sample implementation yet?  I would think that there'd
need to be at least one well defined key in the dictionary so that the
kernel would know which subsystem to direct the request the dictionary
once it got it.

I'd like to see more than "copy and paste this" before consenting or
objecting to it being added, although as I said I like the concept.
