Posted something similar on TMC, just adding it here in case anyone missed the rational for making supercharge.info open source now:
Map related suggestions have been pouring in. I have an inbox full of offers of help and suggestions for alternatives.
Trouble is, I created supercharge.info when I had no children, but I now have two (2 years old and 6 months old). I’m having trouble finding time to evaluate alternatives much less write code for them. I think it is time to open this up to a community and let any interested programmer contribute.
