ownerOnly modifier and ending the auction

We have never used the ownerOnly modifier. Is it intended to be used with the end() function? If yes, then how would bidders force the owner to end the auction?

Also, if there must be a user invoking end() function, who should it be? In the end, whoever that is, he/she pays in gas for this. Is there any way we could make it automatic or how would we address the issue?
