I think this is potentially quite dangerous; There are a lot people who get very twitchy at the idea of software that Phones Home. I've seen this so many times, and in all cases it was for software a lot less sensitive than a database. I'm sure you've already considered this though, you're already talking about anonymity, and transparency, and what I assume is neutrality of the collection endpoint (can apache actually provide a VM; is that a thing?). I'm just afraid that we'll scare people off before they can be properly convinced that it's all on the up-and-up. I'm curious to see what others think, but at the moment I'm hovering somewhere around a -0 if it were opt-in (off by default). -- Eric Evans Acunu | http://www.acunu.com | @acunu
