Geoff, I wouldn't know what to do with the SQL tables if I had access to them. I'd love to learn, but I do not currently have the time nor the patience to sit down and do so. Maybe in a year when I finish up my PhD, I can look into it. 
All John and I have discussed is a method to keep track of who has downloaded the apps and how many times. We may be able to determine that based on who calls to Carrona.org and how often, but that would be a different set of statistics to find out who is using the apps and not which version, etc.
I also think it worth noting that users should be given the option to opt out of such statistics since it could be considered Big Brother behavior.
