I currently use the MSR Pocket Rocket.  Is that compatible with the Outback?  Can the Outback be used on a grill over an open fire?

It is compatible because the pocket rocket has excellent simmer control. But here's what I didn't like about it:

1) The surface area where you place the pan is small in diameter. It is easy for the bake pan to slide off and onto the duff and dump your cake onto your sandal shod foot or upside down onto the ground. That never happened to me but almost. A pair of gloves is very handy with the outback oven.

2) the pocket rocket concentrates the flame in a rather small area. If your not careful you could burn your delectable delight.

3) due to the canister being directly underneath the oven I thought the potential for an explosion persisted.

For these reasons I picked up an MSR wind pro and am glad I did. The fuel canister is remote. This does 2 things for you. The potential for an explosion is gone but it also lowers the height at which your food is prepared. Less chance for an accident both in terms of it falling on your foot and dumping onto the ground. The wind pro also has a very nice wide burner. Much wider than the pocket rocket. Better and more stable. And lastly, as the name implies it is intended to be effective in windy conditions due to the wind shield. It is now my primary stove because of safety concerns and the pocket rocket is regulated for what it does best, boiling water in a 16 oz stainless cup. Since you will have the burner on for long periods the pocket rocket would waste much fuel....not so with the wind pro.

drawbacks? You have to store it in something so it doesn't get damaged unlike the excellent storage system of the pocket rocket. I put mine into my pot.....works great and I do suggest it.

The results with the outback are surprisingly good. We usually make double batches as it fills the pan well. We always intend to save some for later but somehow the whole double batch ends up gone within the hour. If your going to have leftovers make sure you have odor free storage. I use a little GSI lexan storage box with a rubber seal. I usually never have to use it though. Notice how the weight is starting to creep up? It's fun though and the results are great.  

I think you would have to be careful about putting it over an open flame. I think it would be a little tough to keep it in the "bake zone" as well. But that's just my opinion and having never tried it I probably am not qualified to give good advice. Just a hunch.
