I have thought a lot about it. Our architecture goes against that model, but it wouldn't be impossible. I just don't have a good visual for what the UI should look like. Our users clearly don't care about which relay is doing what, so I would need to turn them around to think about relays first.

My thinking currently is large tiles with an image, kinda like the youtube thumbnails, and hope that relays will advertise themselves (function, subject, domain, whatever etc.) visually.
