no, i don't think that's accurate, from what i've read.

so, these are clothes designed for a particular simulator.  but i don't think they're conforming at all, which you can do in Poser (make hybrid clothing). in fact, i'm pretty sure hybrids are not possible with the D|S system.  if so, they've been oddly quiet about that feature, which isn't like DAZ or any successful company.  and it especially seems impossible because the dynamic system is licensed by DAZ, not made by them.

the issue is more that DAZ chose a very proprietary system to use, and those people usually charge thousands of dollars for their system (again, from what i've read- i haven't done my own research).  so they have a business need for a more closed system_and_ have a technical need due to more complex conversion than Poser.  the same is true of basically all D|S technologies.  you can edit Poser's internal files, but D|S makes binaries you can't edit or deconstruct.  that way DAZ gets to do what they want without worrying about how people will hack it (like how the Poser community exploited a bug in Poser to create super-conforming clothes), and they have built-in protection of their technologies. 

but you can actually use the clothes in Poser, from what i've read.  i can't remember whether they had OBJ sources or you just have to export them as OBJ files.  either way, it is possible to make them into OBJ files, in which case, yes, you can bring them into probably any 3d program and do what you want, including use them as cloth.  i would suggest that if the OBJ has useful groups, you use them to set up different types of dynamic groups in Poser, but that's just a guess.
