That would be great. Unfortunately it must be extremely difficult, seeing how long time the big 3d packages have been around and how many renders people have made, but still hardly anyone of them have dynamic hair in them.

However found this one, which i think is just amazing - Gorilla

An nvidia is working on something as well, but seems to follow the rest of whats available out there, meaning its going to be just as difficult. But can always hope - Nvidia hair

But again they render and simulate very well, now if they just would make them easier to use :D
