I totally dig where you're coming from. When I buy content from DAZ I always download the zip (rar) file and install it myself. When I know I'm going to be out for a few hours I might set up the DIM to install the DAZ stuff. I do end up with dual installations sometimes but I have Huge external drives so I don't mind. The only issues I really run into is converting stuff that has no PoserCF files. DAZ is NOT ensuring compliance with PP11.

How are you doing your large scene files? For my biggest most complex scenes I used to use layers. The battle with Cancer (not me buy My Love) took years but I'm ready to get back to my own comic as well.
