Yea, that's my #1 concern now that I know its worth pursuing as a more well developed product. I'm hope to step away from PHP totally for the next iteration. This was more-so a proof-of-concept for the sake of feedback.
I was thinking about not forking processes to read a file, not to avoid the use of php, if you're comfortable with that.
What ideas do you have about reading the stats? You'll have to use a server side language anyway (or do you plan to read data from a third party service with a restful api?)
edit: if you want to have a zero-install tool I'd suggest to go with python plus bottle (a one file webframework), so that you would be able to clone and use it from any directory.
