Drop kick for kickoff

[With_Two_Flakes]

If it is considered that this play might be legal (ignoring the possible offside by the kid who starts it off), then perhaps we should take it to its absurd conclusion. How much of this messing about with throwing the ball from player to player WOULD be allowable? Would it be allowed to be thrown backwards by A1 to A2, then forwards by A2 to A3 and then kicked? What if there were two forward "passes"? What if it was batted to the eventual kicker?
Would the only consideration be to kill the play if they exceeded the 25 second count?

I'm not a Fed Rules expert, we use NCAA over here in Europe. I can't find a specific rule in my 2010 Fed book (or indeed in my NCAA book) that I could say specifically outlaws this play. But for me, common sense deems it illegal. My gut feeling is that once the ball is blown ready, if they want to drop kick it then the kid who kicks it better be the only one who handles it. But I have no rule reference to back that up.
