Some people say the tackle box is tackle to tackle, but I think it's 5 yards on either side of center. If a rugby style punter kicks from outside of the tackle box, he can be tackled as he kicks or right after he kicks. Different rules outside tackle box even for punter. Also, I think the roughing rule ends when the kicker regains his balance, so that a kicker that has kicked and is back to being on balance can be run into a bit. I think this is why some things that look like they would be roughing aren't call, i.e. because the kicker has regained his balance and just gets bumped a bit. Doing what the MVS guy did to our kicker isn't allowed, tho.
