Gods, I LOVE this feature.  Along with P7 rendering a scene that P6 choked on every time, it's rendering in the background right now while I'm reading my mail and writing this!

Also, for anyone having problems merging pz3 files, here's my solution:

Open the first one (make sure you have your external runtimes attached if you used them) and save it.  

Open a new window.

Close out any runtimes you didn't use with the second pz3 and then open it.  

Delete the lights in the second one and then save it, as well.

Open a new window and open the first pz3.  You won't have to attach any external runtimes because P7 now knows where everyrhing is.  Then merge in the second pz3.  You should only have one set of lights and P7 shouldn't have to look for anything.

I just tried this with the scene I'm rendering and it worked for me by doing exactly what I just wrote.
