Haven't tested it with replica sets, it will probably not work. You're free to implement that though :)
I thought about making it a hosted service, but I wanted to release a minimal version and see what the feedback is, so I decided to make it open source instead of putting a credit card form on the page.
That's cool. I've been split for a long time between close souring my stuff or making it open. My gut wants the things I make to be free because I love getting other people involved, but my brain wants to keep things closed so I can make $$$. But really we all are decent programmers, finding work and making money isn't a problem. If I had tons of cash I'd still spend my day programming and the rest with family and friends. So what's the difference? yay open source. Let the people who haven't figured 'it' out yet kill themselves to make more money and then wonder why they still aren't happy ;) /end rant
Why do people seem to assume that open source != $$$?
One of the biggest problems I have with open source is finding help fixing problems and just getting support in general. I'm happy to pay $$$ for software as a service, key word "service". Open source is a value add to SaaS, not the other way around!
I don't think he meant making money through supporting the service -- rather, you can make money for software as a service. Unrelated, that may or may not require offering support.
In addition, there are TONS of people making money off of open source. Hell, that's the business model of almost every web hosting service in the world. No reason you couldn't.
