Rolling attacks for poison and the like is kind of unusual and a bit awkward. I find that the consistency gained from having a single system more than makes up for that awkwardness, though, and toyed with hacking it into 3e well before 4e was being written. The Poison is "attacking" your Fortitude, and the trap is "attacking" your Reflex.
Mathematically, a saving throw and an attack vs. a defense are identical, and if it's not "actor rolls" like in 4e, I'd prefer something like Unisystem where the players roll all the dice - rolling to attack and rolling to dodge vs. static monster attacks or defenses. (Damage would still need rolled, however.)
Basically, I don't think "who rolls the dice" should necessarily model anything that's occurring in game. Rolling is itself a gameplay convention, so I'm more interested in ease of use at the table.

There is also the third alternative: everyone rolls. Much more swingy, though.
