Dendrobium no ID. Does anyone have any idea?

[stefandeak]

Okay so my wife's mother got this from her neighbour. Then, knowing I grow orchids gave it to me to figure out what's up with it and divide it, and told me I can keep half lol.
I got it like this, broken canes and everything. It even has some neos thrown in in that mush at the base.( Benefits of living in japan ey?) It has obviously been grown outside.

I know there's not much to go on but does anyone know what this is? Should I just treat it as a nobile until it gets into better shape and gives me some more clues? A repotting is definitely needed, should I use bark or just do it in a basket like it has been growing so far?
