Jack: I use a one-bottle belt from Amphipod. It carries around 16 oz and the bottle fits into the small of my back. My son uses a four-bottle setup because he likes to have both plain water and sports drink, but I go with Gatorade G2. The belt also has two small zippered pockets for my gels, tissues and drink powder, and I can move the belt around to the front to get a gel and the move it back. I adjust the belt tight when I start so it doesn't bounce much at all even when it's full. It loosens up somewhat as I'm going, but since it gets lighter as I drink, I don't notice any more bouncing. The multi-bottle setups are probably easier to reach because they aren't behind my back, but this works well for me.
Regarding refilling the bottle during hot weather, I plan my long runs so that every few miles I'm going past either my house or our city park with its water fountain and toilets.
urun2me: I'm glad you fixed the gasoline/vaseline typo. Otherwise I would have thought you found the miracle chafing remedy.
I've been fighting a head cold for the past week, so no running. By Saturday, I couldn't stand being cooped up, so I went hiking with a group from my bicycle club (we do hiking/snowshoeing during the winter). Yesterday I was so congested that I could hardly breathe, but it was worth it just to get outside.
