I'm trying to come up with a nice sky effect and have the suggestion of
projecting a movie of clouds on a dome (hemisphere). What I'd like to
toss around pro's and con's...

A hemisphere will have to be a fair amount of polygons I think... How
efficient is Gouraud shading an animation on a dome?

And the video will have to be taken with a fisheye lens to get the
horizon looking right...

And the animation will probably have to moderately high resolution
because you might have the whole dome in view at once (lying on your
back in a park).

Last of all are there any nice hacks to make this faster?
