Poser python scripts won't run in DS, no. I must seem a pain being one of the few DS users in here right now, but there's a lot of us out here, and a lot of us love what's been done with Antonia too. For freebies, it doesn't much matter how the morphs are done. Some will download them and go through the extra trouble because they're free or just do without. But for vendors, the extra channels so they can do a regular injection pose may make the difference in their sales. I know I may go through the extra trouble to use the PMD script for a freebie I really liked, but I would skip on buying any product that used them. If I'm going to pay for something, I want it to work in my app of choice as easily as any other product I'd buy.
