Here's a sketch of the order I imagine I'm going to climb this mountain. I the course to change as a I reveal more of the terrain:

1. Build a multi-choice poll type for timestamps
   • involves ssb-poll-schemas and perhaps scuttle-poll
2. Build an interface (similar to Doodle)
   • set up a new poll
   • contribute to a poll
   • close a poll (announcing a chosen time)
   • see an overview of polls (optional for v1?)
3. Have a poll generate a gathering
   • review the state of gatherings code
   • perhaps consolidate work from across the ecosystem
4. Extract the calendar from patchbay
5. Build standalone app
