Any interest in developing an open source fuel economy gauge/computer?

Are there any people here who would be interested in developing an open source FE gauge/computer?

We see lots of inquiries about the SuperMID, which works by monitoring the vehicle speed sensor and a fuel injector signal. Unfortunately, Yoshi's a busy guy, so he hasn't been building too many. And the value of the US dollar relative to the Yen is making the MID more and more expensive.

I don't know much about this stuff, but it seems to me the open source Arduino computing device ($35) would be an ideal platform. The cool thing about it is that it could also be connected to a laptop/palm if desired.

I know skewbe @ GS developed a quick 'n' dirty FE gauge that uses a laptop sound card & audio input to monitor injector cycles, but an Arduino based system seems like it would make more sense to more people.

Doing something like this is outside my experience. I could probably figure it out, but I've got enough projects as it is.

So I'm just putting it out there to see if anyone else would want to spearhead things.
