Personally, I could care less if the content is in Daz format or not, all I'm concerned about is will it work in D|S without too many issues. Most D|S users know and expect certain things won't work as expected. A simple warning that the product uses Poser specific lighting say, or shader node textures would suffice I think.

But the point that is being made is one that should be considered...there is a growing number of Daz users, especially as the program develops and improves. Since I started posting here (since 2005) I've noticed the Daz gallery grow quite rapidly. I don't suspect it will cease to grow any time soon either unless Daz does something really stupid. The fact of the matter is that poser content can be used by several programs and this needs to be considered in content development....man it must suck to be a vendor some days.
