Yes, but this is a proof of concept. There is currently my DVM and that relies fully on nostr.band (and a second version that gives up to 150 results from a year ago, also from nostr.band). The intention is that anyone can run a DVM and improve results further :). The page collects all events it gets.
In terms of relay hints, please feel free: :)
