Ilford XP-2 and Kodak 400CN

I vaugely remember reading or hearing somewhere, ages ago... that C-41 processing wasn't actually needed and you could soup this stuff in regular B&W chems?
Maybe my memory is faulty? Anyone else remember this article/discussion on what kind of results that might give?

AFAIK, any C-41 film can be processed in B&W developers (with a fixer but no bleach!) to produce conventional B&W negatives. With most films you'll get a dense orange mask. I've seen scans of this type of processing on the Web but I've never tried it myself.
