@dorifer the difficulty level for any software project is largely a matter of the programmer's experience with the topic. I said it's beyond me, but I'd love to be able to lay good foundations for privacy/secure gaming and then collaborate with someone who knows about maps.

It's a fun hobby project, but for it to go past that I think I'd need to figure out what demographic of tabletop gamers are sufficiently concerned with privacy or centralization that they'd switch off the existing platforms.
