PhilC's clothroom scripts work in 6,7 and 8 that I know of for sure, I use them fairly often.  As for Poser Pro and PP2010, no clue, never had either but I can't see why they wouldn't.

And yeah, that looks suspiciously like they just prettied up the freebie.  Heck I think the freebie has more cloth presets in it... Not firing up Poser to double check I need sleep soon and I know I will get into working on something if I open it.
