Please put a lot of money on that bet, because I'd like to win it :-)

Why would those rendering farms use rt-linux?

Rendering is not done in real-time - far from it actually. It can take minutes 
of the entire farm to render a single frame. So rendering is nothing but CPU-
intensive (calculating how all those lightbeams are reflected by each surface) 
- and everything I/O bound is about throughput: writing the rendered pixels to 
disk and getting more surfaces from disk.

There are no deadlines for rendering, there are no penalties if a frame is 
late by seconds - if the farm cannot complete its job overnight, they'll add 
more CPU power.
