I have a similar project I'm working on, and have thought about going after crowdfunding, but decided not to. It came down to a) not having any mentionable competitors in the space and b) not wanting to be one of those people who takes other people's money and ends up wasting it. So I am still working on it, as a side project, a few years later. Sometimes I wish I could devote myself full-time, but providing an open-source privacy app for the fun of it and for its own utility without thinking about paying the bills has made the project a lot more inspiring for me. I don't have to think about the bottom line, just "what would be useful to build next?"

This is what people did before crowdfunding. Maybe we all don't need $100K just to start and publish something useful.
