Hey Exile,
Maybe I misunderstand your question, but I assume that you are trying to move your model in Med. If this is the case, I have moved around models that are already animated with bones.
The way that I did this was to first move the model by selecting the model components in object selection mode. After I had the model in the correct place, I went into bone selection mode, and then tried to line up the bones as well as I could to the original model in comparison to the body. When I did this, I was able to move my model and its bones to a new position without any warping or having the animations get screwed up.
Of course, you can't be in Animation mode when you do the moving, or this won't work. Anyways, I hope this helps.
