Also, to get outside temps. you'll need to sell a thermometer probe like the kinds used with Gentex and CIPA rear-view mirrors that show outside temps., right?

For the right hand clock clusters, there's no place within the cluster to mount it (without cutting plastic). My original thought with this whole thing is that it would really be for the tachless people. It started off as simply a tach in place of the clock and then the more I thought about it the more features that kept popping to mind.

Correct on the sensor probe for outside temp (although if I can figure out the CAN messaging for the A/C ECU, I can use it's outside temp probe and save people having to run a probe wire through the firewall).

I am making great progress on this. I built a CAN bus interface this week and can read the PIDs (all of the standard OBD data), can read and reset stored DTCs, and can sniff the communication on the CAN bus between the ECM and the body ECUs.
