If the goal is to get people to try it out, putting a sign-up for a free trial page between the call to action and the action is at odds with that goal. I don't want a 14 day free trial, I just want a sandbox to play in and I expect it right now.
I'd also think that supporting SQLlite might broaden the appeal.

Good luck.
