Firstly, I'd like to thank everyone who helped me with my first "real" 
water Q.  It works very, very well.  But I now have another problem. 
Although I now have realistic water I can submerge my camera in, it 
takes to long to render.  This wouldn't be a problem normally, but 
because I'm using this for animation purposes rendering speed is an 
issue.  Even if I drop the samples down to the lowest point where it 
doesn't look like crap, I'm still looking at a 4-6 day renders per 
2000-5000 frame animation.  I'd like to keep this to less then 1 day per 
animation.  Without media the animations were taking between 4 and 8 
hours...

So can anyone think of a way to achieve an effect where more distant 
objects look like they're behind fog (i.e. faded, hazy).  I was thinking 
of using a series of partially transparent planes in front of the 
camera, each one with a rough surface to make for some turbulence.  I've 
tried a few different implementations of this without success.

Any other ideas (or ideas as to how to make the planes work).

thanx

Bryan
