That has been on the PowerSDR wish list for a very long time. I forget 
the details now, but I had a nice chat with one of the software 
developers in Austin and he explained that this is a very non-trivial 
enhancement, so don't expect it any time soon.
Where I would really use it is when 6m is open. You get a picture of 
where everything is happening with the waterfall and panadapter, and 
that mental map is lost when clicking on a station up the band.
Having multiple receivers available now helps a lot, however.

I haven't played with cuSDR yet. It sounds like a really nice piece of 
work. As I understand it, it runs (mostly?) on the video card. I haven't 
seen info on what level of video processing is needed, but it is 
something I should try.
