Fistly, providing the source does not make a program open.

I stopped using POV for large print work a long time ago for the reasons you
seem to be missing.

Say for example, I wanted to render an image that makes heavy use of
radioasity and print it as a 54"x34" poster at 300dpi

I would have to render the image at 16200x10200

Now, on the fastest single CPU I have, said image takes a day to render at
1024x768

How long would it take to render the poster size image (that is more than 10
times bigger) ?

Far to long, especially if you concider that its easy to make an image that
takes longer than a day to render at desktop resolutions. 

And all this assumes that I will only have to render said poster sized image
once, how do I keep a client who wants to see a series of proofs and make
changes - tell them it could take months because povray doesn't scale!

"POV is not a suitable tool" and "simply isn't practical" are very clearly
valid statements.
