Interesting - though I'm not sure how this is different from running LE in manual mode. I'd just cut out the middleman and use LE directly.

I don't understand your particular concern on "auto-mumbo-invasion". The LE script needs root access to write to /etc, to write to web server config files if needed, and to bind to a port under 1024. BUt the whole thing is open source, so you can read through it and find out what it's doing. Personally, I trust the EFF and LE more than I would trust, say, Microsoft or Apple.
