Any plans on open-sourcing the code? I'm not sure if your intention is to build a business using it (or, if you were, using AGPLv3 might help prevent third-parties from unfairly competing with you), but I'm sure a number of people would be interested in trying to run this on their own hardware, building their own personal index, hacking on it to add features they find interesting for themselves, or otherwise just learning something by taking a look under the hood (I'm probably in this category myself).
