I may have misunderstood the basis of your question; but I'm ploughing on regardless. :) I don't have much experience of animating dynamic cloth to produce an animation, as opposed to animating to drape it for a still; but I'd expect that dynamic clothing that was set up for an animation would also function well in a static render. When making a still picture, the number of frames in the "pre-animation" would be important, but I don't think you can enforce that except by making suggestions in the readme. I haven't seen anything like that so far in dynamic clothing that I've bought or downloaded free.
