It would be cool to see relays that also act as proxies to all other known relays.

This way, rather than syncing *all* data with all other relays and using a lot of bandwidth/space, it would get a request from a client to look up posts from a particular user, and it would then ping all other relays for that users posts.

Is this possible?
