I see more promise in integrating it into Nostree.me (but I'm obviously biased since that's what I'm working on). Good news is that they could use the same spec (although it seems like @Sep made a specific event kind for his boards)

How does pinstr handle it? I can't seem to find a NIP for it I see the kind 33889. Anyway, it is pretty close already but maybe the scope is different? I'm not sure... 🤔

Nostree it's pretty good for a replacement of carrd.co and similar, maybe it can be extended with a section to collect media?
