Hi Dan,
Have you seen Camelbak's or similar lower priced clones? You carry the
water on your back and then drink from a tube. They are great for
biking so you don't have to actually grab a bottle although the
disadvantage of course is you have to carry the weight of the water on
your back. Perhaps you could adapt the hoses from one to fit a
container that will go in a water bottle holder.

I actually found one of these, like the ones goalies use in the NHL.
It's a quart plastic bottle and I'd be happy enough with it except that
the water tastes like plastic. I did a little looking (REI and
Sportmart), but they didn't have anything like it. These have a tube
that you drink from that goes down to the bottom of the bottle. So, when
you squeeze the bottle, it forces water up from the bottom of the bottle
through the tube, so you don't have to tip the bottle to drink from it.
There's a vent at the top. I'd think these would be readily available
but haven't seen them except the one I found in the street - probably
because the previous owner didn't like the taste either.
