Lighting Group Speed

I wish I would know all the details of OZWCP, I just stumbled over it as I found out that this tools lets you see which device has which other devices as neighbors. I didn't expect it to run a full route update on my existing network. Don't get me wrong, I am glad it did as I am sitting grinning over the speed of my routines now.
I am going to see if I can find some more information on OZWCP. I basically came to OZWCP via this thread: Z wave mesh frozen completely and have about 10 minutes of experience with it...
