I'm writing some stuff to handle a couple of different IButtons
(memory, clock) using the Dallas/Maxim serial port adapter (the
new one which uses the DS2480 chip). This adapter and others are
well supported by a rather grubby C API, and I couldn't bring
myself to work in C only. So I've created a Ruby extension to
wrap it. Or at least the bits I've needed so far...

Just thought I'd put out a feeler to see if there's interest in it
from others out there. Especially if someone wants to extend or
maintain it... ;-). I know that the one-wire interface is used by
a number of commercial and home-brew weather stations, for example,
and also in temperature monitoring. I can't add support for those
devices since I don't own either.

As far as I can tell, the API it wraps doesn't seem to allow
linking programs that can choose which driver to use at run time.
You must link it to use the USB driver *or* the serial driver :-(.
I don't plan to fix this, so the Ruby wrapper will be only for the
serial driver that I have.
