Yes! We're working on it, both client side and server side.
We've got WKD working on our own hello@fluidkeys.com email address using a rather cheeky hack[1].
Server side, we're adding this to Fluidkeys Server soon.
That way, teams that use Fluidkeys could redirect `<team-domain>/.well-known/openpgpkey/(.*)$` to our server, and voila, we'll serve their keys via WKD
