pcmonk - royce here. Would love to connect. I'm basically building a super simple service for churchs and their members to interact starting with automating tithes and offering. Love to chat more about it - royce.haynes@gmail.com.
I'm basically the tech guy for my church, and my parents are elders (we don't have a pastor, per se; we have four elder couples).
I think that's an interesting idea. The first thing that jumps out at me is that it better be very simple to use, and there should be a way to integrate it well with the church website, regardless of what system they use to run their website. But, I'm sure you've thought of that already. I don't think this would work out well for my church since we're pretty small at this point (about a hundred attendees most weeks) and not particularly tech-literate, but I'll keep an eye on this.
