Has anyone combined the rocket mass stove and earth bag concept?  maybe running the heating tube inside the wall, or building a double thick lower section of the wall - maybe 1 m tall - and building the rms in that?

The "My Little Homestead" family built a rocket mass heater in one of their earthbag structures.

They have built several, but the rest are not so directly integrated with the earthbag wall.

Thanks!  That is exactly what I am looking for.  I don't know how practical it would be, but I would like to make every third layer of my eb house with a hollow space in the middle and run the exhaust tube through that...to heat up the whole wall.  i wonder if that would destroy the integrity of the wall?

It would certainly lessen the strength of the wall compared to a solid wall of the same thickness, but making an earthbag wall thick enough to fit a duct would cause it to be significantly stronger than usual. So I wouldn't be too concerned about strength.

This idea would be giving equal heating to the interior and the exterior, however, effectively cutting the usefulness in half. I think you would be much better served by doing it on an internal wall. Alternatively, I would insulate the inside of your wall and add the earthbags with duct run inside that.

The wall would be an internal wall - maybe between the living room and bedroom.
