Yup. As Bill said, I'm sure there is considerable interest.

Whilst Tiny's Furry Cats are fantastic, the level of skill and patience involved in creating those using Poser's hair room is considerable and beyond most people's thresholds, time-wise, even if not skills-wise, I think.

I'd buy your plugin on the basis of it being able to do good fur alone. Any further ability to make better human hair, even if just for still images, would be a bonus. But even if fur was all it did at first... I'd feel more confident in your continuing to develop and push the boundaries, I think?

There's a reason that the high end 3D CG software like 3DS Max rely so heavily on plugins like Shave an Haircut to deliver. The distributed developer ecosystem allows levels of specialism that cannot be attained by one development team alone... seems that way to me at least.
