Vending machine cube to activate permission block

here is the idea:
connect your vending machine block to a permission block to set a price, a numbre of uses and/or a time of use.

it could also somehow aload to atribute rewards (on new race highscore or on predefine logic setup for exemple)


This could aload :

-nanotech "drive in"
-toll warpgate (love this one)
-CASINOS !! (nothing impossible through logic ^^)
-vs watch races with rewards

-much more i guess...
