I'd be REALLY happy to host such a list on the http://ArduinoInfo.Info
WIKI. But I know I can't spend much time on it and I hate to start something and not follow through.
The WIKI has benefited from help from many people like Crossroads, Grumpy Mike and others, and I'm fine with putting up a page like the Arduino Pin Current Limitations (http://arduino-info.wikispaces.com/ArduinoPinCurrent
) or the Arduino and Mega Quick Reference (http://arduino-info.wikispaces.com/QuickRef
) but that doesn't take much upkeep.
If anyone is interested in starting it up, let me know and I'll start the page and you can join the WIKI and edit anything you want...
Maybe someone could start with the Teensy list...email@example.com
