I'm liking the thoughts on the Jedi Temple. I agree completely that the Jedi Order would surround themselves with life, rather than some lifeless monument.

I think it best if Yoda is always on Dagobah and has been for a few hundred years. Jedi go there to train with him but he never leaves the planet. I imagine Yoda meditating and sensing the events in the galaxy through the Force. I also prefer the idea of the Jedi Masters communicating through the Force and, perhaps, the council itself meeting in that way.
