Short answer: agreed. Either 1) spec what you want and we'll try and
add it in prompty, or 2) submit code to be included.

The nice thing is that there is nothing *terribly* special about
plumbing.module. Any code you write can easily be included if it makes
sense. So, just develop PROCs, and then we can think about where they
might go if they are useful in the general framework.

Related: if you want, we can give you a directory in the "community"
directory of our repository, or if you put things in somewhere we can
get to (eg. github), we're able to interact with you more directly on
code questions.

(That turned into a long answer.)

Is this an Uno? Christian and I were just talking this morning about
how we seem to have a serial issue on the Uno that we need to correct.
My guess is it's pretty simple... but, it might not be.

I would love to see more work on it, but haven't myself had time. I'll
be talking about some related project ideas with students this term...
we'll see.

Cheers,
