good i am tired of talking about gas as well....lol....this functionality was realized by hugpuddle.org before #ethereum..
we didn't think that an entirely new class of blockchains or gas was required to do these types of things.
we are releasing  0.4.0 this year designed for a larger much less technical audience.    (the world)  lol


trust is accomplished by signing a hash of the application transactions using bitcoin's or the altcoin's internal signing function and including the signature with the transaction... monitors perform the same function in reverse comparing the hash to the signature and if they match and if the address is a trusted source then the transaction is executed if it's executable......if there is no signature or if the signature doesn't match it is ignored..
