There are things to hide behind in the middle of combat in an open field in the daytime. Your opponent, for example. If you want to give people who are farther away from the action ginormous bonuses because they have a good angle on the action, that's fine, but out-and-out claiming that it is impossible(or even stretching the bounds of probable) is clearly false.
But that's not how hide works. Hide works such that the closer you are, the better chance you have to see something. If you're talking about something done in a melee which relies on misdirection, you're talking about a feint. Whether its simply quick swordwork or a tumbling misdirection to cause you to lose track of your opponent is mostly irrelevant. The point is that it's something you do in melee to remove your opponent's dex bonus. And that actually perfectly describes Ess' example.
Seriously, RC, even if you're right, and it's absostinkinglutely impossible to just stand 5' away from someone, in an empty room, and hide from that person just b/c you're really, really good at hiding, why can't you do it in D&D?
Mostly because flavor wise, it's directly contrary to what you want the fantasy rogue to be doing. As a rogue, darkness should be your friend. You should be the guy lurking in a dark alleyway pilfering stuff at night. However, under the 3.0 hide rules this wasn't so, you were in fact best during the day, because concealment spoiled your sneak attack. And that's exactly what allowing rogues to do that in the day does. Basically if you're invisihiding, you've got 50% concealment, because you're effectively invisible. If you can do that anywhere under any conditions, you don't want your enemies getting concealment, because you've already got it, so all rogues are going to be doing their work in broad daylight and that's incredibly dumb.
If people just want a way to take cheap sneak attacks at people in combat, I say we just improve the feinting rules (feinting sucks bad in 3.5 anyway right now). Because that's really what the misdirection styles you're talking about are all about doing. It's not about sitting in a corner hoping the guards pass by. It's about killing them while you're standing right next to them. So why not just use the feint rules? They fit much better than hiding given that you want to represent misdirection tactics in melee combat.
