Search "hop tea." Another advantage is that it takes a week to dry-hop but only 15 minutes to make a hop tea.
One other approach to take, if you naturally carbonate, is to hop your priming sugar solution. That way, all the hoppy goodness you extract goes right into the final beer! The one time I tried this, I actually made a kraeusen beer. Since it fermented a tiny bit before it went into the keg, it technically did get scrubbed some.
