This is pretty useless:
I can't tell what host each working copy is running on, nor the repositories it has cloned. Since working copies never expire, I'll need to at some point go and clean these up. In order to determine which ones need cleaning up, I want to be able to know which repositories they've cloned (so I can clear out old ones).
(The details on each resource show the raw PHIDs for host leases / repos, but those can't be lined up with anything useful in the web UI).
