Ive only been poking around at the source code. with no interest from anyone to help I was going to leave most of it until next summer when I have more time to do it on my own but certainly if I’m getting any help then I’d be willing to kick up the pace right away. I’m also very familiar with Apache cassandra,writing a book on it in fact. So if you’re team has no ties to mongodb then even better. Although I should be able to easily learn the ons and outs of mongodb. Please let me know if this can go on, I’d be very interested in being a part of it.

I’ve included my correct email above. Drop me a line.

I had already implemented a command of my own to automate the sequence. Thanks!
