I just got this link from Lindsey at Austin Energy's Electric Vehicles and Emerging Technologies department:
https://data.austintexas.gov/Utility/Electric-Vehicle-Charging-Stations-Map/hgcc-vrrw
Supposedly an up-to-date map of the Plug-In EVerywhere locations. I'm currently in the process of comparing it to the Chargepoint and PlugShare maps for discrepancies--will report in with what I find. (who, me? a geek?

Cheers, Austin!
