I was wondering if you can stream 3d anaglyph movies from anywhere online legally?

I don't know if any of the major outlets have a 3d service yet. I did see vudu on my ps3 offers 3d. HOWEVER it won't even play a preview - it simply says 3dtv not detected and won't do anything.

Why wouldn't anybody offer anaglyph versions for online streaming? It can't be anymore complex than doing regular streaming.
