   This is not some exotic technology.  Look at the soda fountain at your   
   local McDonalds, it also does exactly the same thing.  Gas coming in at   
   a few bar, not at crazy high pressures, going into a small jet which   
   accepts water coming directly from the city mains and spits out soda   
   water instantly in realtime.  (There is also a venturi gadget which   
   pulls syrup from the bag and mixes it in; this makes gas pressure critical   
   since changing the air pressure changes the mixing ratio).   No more   
   pressurized Cornelius canisters, just bags with negative pressure.   
   Just buy soda fountain hardware because it does exactly what you want.
