I never saw anyone use a 3.0 PH at a 3.5 table. The changes between those editions were much more extensive than originally billed, and the conversion guide extensive enough that I wouldn't want to try to reference that mid-game.
I'm not saying that it's impossible by any means. Or that the two editions are totally incompatible. DM-side, in particular, I'd feel pretty comfortable, say, updating a 3.0 adventure on the fly to 3.5 if I wanted to and was currently still expert at that rules set.
But IMO it's really substantially different from the 4E/Essentials update, which was literally a few rules updates and some new classes and options for the same game.
