trade him for cap space or trade him for most available talent?
like trade him for someone like Jason Thompson (http://games.espn.go.com/nba/tradeMachine?tradeId=3ey7uk6 ) and get 9 million in cap or trade him for Jameer Nelson and Bass.( http://games.espn.go.com/nba/tradeMachine?tradeId=3dx6zoh ) and get more talent??
I'm sure there are other trades out there for smith these ones were just good examples of what could be acquired talent or cap.
