There's a specific note type in the protocol for calendar events, if that's what you mean? We just need more clients to support it to grow adoption.

Yes like a calendar entry and even a geotag for radius filtering? I’m gonna dig into Seeker and Flockstr and see how they’re doing it 😎 there’s a little app called Farmish that I love that puts their listings on a map. That would be a cool idea for social gatherings too.
