I'd be tempted to roll all those queries together, and then extract
the items from the one result string - just to cut down on DB load.

Unfortunately set= isn't available in a transport; only in a router
or acl. You could hack it via an acl expansion, or you could
just rely on the lookup caching.

I probably should add set= in transports, now I've seen this.
