I've not put a ton of thought into a plan to open source it, but we've got comments from friends who also have a lot of genealogical info that it would be super helpful for their info, so maybe? It's basically just a CRUD Django app at it's core, so I don't know how interesting it would be.

I think a lot of people would be into this. If you're willing to, you should totally do it! You might get some good contributions from the community, too.
