I agree that it is probably in violation of the spirit of the rules, and this actually isn't a strategy that has even been discussed by my team--just something that came to mind while reading one of the Q&A responses.

As far as being in possession of more than one game piece--as the definitions currently stand,

POSSESSION -- ...A GAME PIECE on the floor is considered to be in the POSSESSION of a ROBOT if it contacts the ROBOT at more than a single point.

ROBOT -- anything that has passed ROBOT inspection that a TEAM places on the field prior to the start of a match.

By those definitions, the game piece is not a part of the robot and thus pieces on the floor being pushed by another game piece would not be in the possession of the robot.

EDIT -- OK, Robby, I see your point, where herding is not dependent upon possession or its definition.
