It's sort of the same thing we were saying to the dude a while back who said "I dont use a shot rotation." If you melee as a hunter in solo, you'll have longer fights AND more down-time. Which the "fun" of could be equally as good on a rogue. If you melee as a hunter in PvP, where you need every trick you have, you are going to lose. Unless the opponent is a real idiot. And in group PvP, your group will be pissed at you. In group PvP, not only will everyone call you a noob, but they will probably kick you from the group. Also, any slack you make will have to be picked up by the rest of the group - either other DPSers will have to do 50% more apiece to keep up, or the healer's mana pool will suffer. If they can't keep up b/c you want to be "unique" you could wipe a lot. If anything, try a melee hunter at like level 20, not level 70 when you can get one-shotted if you try to get off a mongoose bite.
Although... in hunter vs. hunter a melee hunter MAY be able to win, if you can keep the opponent in close. But that's like taking a sniper on a FPS and running in Close-Quarters (granted, I used to do that on Americas Army cuz only snipers got pistols, and those were my best guns, but that's a different issue and game). You wanna play up close, get a sub-machine gun (i.e. rogue) or a shotgun (i.e. warrior), but don't use the sniper (hunter).
