Though I am not likely to shift to a windows box for my TV watching so I won't be beta testing Sage. The point however is that with a PC platform based PVR, "space shifting" is a trivial feature -- it's called "file copy." (Not that Myth, which its default cryptic filenames, puts a good UI on that, but that doesn't alter the point.)

So it's good to put a better UI on it. The only complex part is doing a live transcoder for limited bandwidth remote viewing if you want that.
