Rubicon, I am sorry to here that you didn't sell your product as you hoped, if only for your effort to do a DS-version; but there is one thing which kills me very time: DS is free! No money spend, so at least a vendor could do a testrun in DS and state on the product page if it works or not!

I know the biggest problem and difference is the  render-engine, a DS-user knows this as well (or should know), but most of the time we will find a work-around, use a plug-in ...., but there are as well morphs that do not work correctly with DS and this cannot be solved (as far as I know).

So 30 minutes to test a product in DS and a mention on the product page (100% DS, Shaders not working in DS, Not working in DS) could help to take a decision if to buy or not.

And a growing comunity would feel better as well! ^_^
