I am not a climber and probably will never be, I enjoy fiddling with stove design.
I became interested in hanging stoves a few weeks ago after reading a comment about hanging stoves on an Australian Bushwalking forum, the comment reminded me of liquid feed stove system I started working on about five years ago, as can be seen from the photo I put a Pocket Rocket stove on the base of an upside down canister, part of the idea in doing this is in very cold conditions there is an option to put some of the reflected heat back into the canister, for some reason I shelved this idea until now. While I do not climb I can see some advantages of hanging stoves in some cases in backcountry snow camping.
A concept prototype
I started my recent hanging stove project by making a simple hanging stove bracket to hold the canister upside down, I then made some legs and a pre-heat tube modification for a Gnat Ti stove (called Kathmandu Backpacker Stove Titanium here in OZ), the legs have been made to clip on the base of the canister. This worked well except the Gnat stove has something wrong with it and I have difficulties with simmering in both the upright canister configuration and liquid feed configuration., I have since replaced the Gnat with my favorite a Kovea Supalte Ti stove and all is working well.

My cheap remote canister stove then turned up and with the current hanging plate the new stove fitted very nicely on the base of the canister, but I will point out that at the moment this is just playing with design and I realize that with this system would be difficult to fit a wind shield and pack away.
Hanging the Chinese stove
The next part of my hanging stove project was to use a JetBoil Personal Cooking System (PCS) with a liquid feed modification that I had done a number of years ago will before JetBoil came out with the Helios I have used my modified JB stove in winter in Australia a few times so I know that it works in cold conditions.

I needed to hang the canister on the base, so I machined up a bracket that screwed onto the plastic shroud, the bracket takes the std JB 100g canister, I did the machining so the canister clips in so it does not fall out while it is still easy to put in, and that it would still fit into the JB PCS pot.

I then needed some way to hang the JB stove, I did not want to buy a JB hanging kit as they are expensive here in OZ, so I got a some spare tent poles and some SS wire form the local fishing store and made a rough copy, while the hanging kit is OK for display purposes I would not like to assemble it on the side of a cliff at -20ºC, some more design thoughts needed here.
All packed up
Where to next, as I am not a climber but I have been doing some research on hanging stoves to try and understand what is needed, I have also been in contact with a British Climber to try and get an understanding of what is needed. So far I have found a few ideas, one is using a larger pot as the windshield, this seems to be very popular and I have seen this done with backpacking stoves, I have also found that my idea of hanging the canister upside down under the stove is not a new, it was done very nicely to a WindPro stove by Longshanks in Denver and the idea posted on a climbing forum last year. http://students.washington.edu/climb/forum/viewtopic.php?f=19&t=5759&start=0
I am combining this project with one that I have been thinking about doing for a while and that is windscreen design.
This project will continue.
