This. I would like to know of the roll only if it was a successful one. Otherwise you fall into metagame trying your luck with every character and animal companion in your party, it's ugly to see. If I failed to notice something why should I be able to call all of my pals to make them do the same check?
Depends on what rolls you are talking about - if you are wandering round areas then i think its only fair that everyone in the party makes a roll to see if they notice something, its not as if the guy with the highest perception is going to be the only one trying to aware of their surroundings especially in somewhere dangerous. In fact I wouldnt mind if you got a roll each time you passed the area given that your equipment/skills might have changed in the meantime.
