Why not dream really big? Poser/DS as a service over the web. I believe that Adobe is already doing this with Photoshop Express. The application and the assets would live in the cloud. You'ld have auromatic access to a renderfarm. You wouldn't have to buy any content, you'ld rent whatever you needed for a scene from a huge selection etc. Getting DAZ etc. to come up with a profitable and afordable pricing scheme would be difficult no doubt, but hey, it's a dream :-)
