Correct, it's a non-intrusive error trapper that gives me all sorts of information on your system when the game crashes. It's written by me and even though the website is currently sorta broken I'm still getting info when crashes do happen.
This is just installed by default for the Beta but once this beta branch goes into the consumer branch it'll be an optional thing. The goal is to crowdsource testing and QA since fans are way better at QA than services you pay for. Eventually I want to find a way to incentivize this sort of crowdsourced help by either paying people, giving them credit in game, etc...but that's all in the future:)
