Just make sure you get potable water/food grade tubing. You'd just have to figure out a way to secure the excess length when you weren't using it, but that shouldn't be too hard.
I am not the most mechanically inclined but I've an incentive here! If I could come up with some way of using this that didn't require head/shoulder dipping...perhaps a way of clipping it to my jersey about where I have the tubing for the Vaude? hmmmmm it would have to be very secure so it wouldn't come unattached accidentally and wind up in the chain, but that sounds like a better bio-mechanical position than having to lean forward. Frankly, the more complicated it is, the less I would be inclined to actually drink.
