Thanks.

It should be.

No...it requires ray and intersection information, so you can't use it 
in functions or media density. I don't think it would be very useful 
function anyway...and I think the media sampling would leave 
unacceptable artifacts, though it might be possible to do something in 
that case.

About as fast as transparent or reflective textures.

Not currently...the only way I can think of to do that would be to 
create a duplicate version of all light sources that is transformed to a 
position that would make it appear on the far side of the portal, and 
only accept direct rays that hit the portal object...and this would only 
work for type 0 portals, and wouldn't be easy to implement. Of course, 
maybe it only makes sense for type 0 portals...
