Screwed? Not unless he doesn't have the normal Hide skill...
How is the normal Hide skill going to help when he's in the middle of a cavern surrounded by two dozen half-dragon bugbears?
I will type slower so you can understand my point

Many creatures have Darkvision.
Many of these creatures live in the Underdark.
Many places in the Underdark have NO LIGHT AT ALL -- not even ambient light from glowing fungi.
In this environment, because there are no shadows, it seems to me that if you play by the book, a Shadowdancer can't use her HiPS ability.
Meaning she will indeed have to rely on her regular "Hide" ability, which is often going to be useless. Not because "Hide" is useless against those with Darkvision, but because normal hiding is *often* useless.
That is to say, a Shadowdancers defining ability seems to me to be often completely and totally negated in the Underdark, unless she brings a light source with her to *make* shadows.
And if she's of an Underdark race, this is pretty silly.
That's all. I've decided to play it that there are "shadows" even when there are no light sources around -- goofy, but I can't think of any other way to not screw the Underdark shadowdancers.
