The technology is certainly there but the workflow of using monochrome inks has not been utilized by anyone as far as I can see by anyone in the POD high-speed low cost press realm.
As Ernst just mentioned they most likely could specialize in it by using gray inks only with a couple of toner channels for variation, but just aren't. Even using one gray channel could improve things a lot but limiting the process to cmyk is not going to work. There is a reason in the offset days we used duotones in the context of book projects where 4 color was also utilized for the color content, and that involved a separate printing with different inks, stripping, and registration.
The problem for a POD company would be people requesting clean neutral bw in the same book as 4 color, and of course everyone would be screaming for that too and that would be expensive with the technology as it stands now.
But with the huge assortment of competing design companies trying to find a market share you would think that at least one of them would specialize in doing black and white only books. There is surely a market there and some day it will be addressed, but I guess not now.

John,
I think your pretty much right on.. The only
thing that makes sense is that their must not be enough volume or market to
raise the bar and go the extra distance to get there. You'd think someone would
have both a B&W and a color machine.. ( probably some do) On the other
hand a lot of the machines that are used are the Xerox expressos.. and they are
basically CMYK machines I think.. So it might be that their just not there
yet.
Conceptually it's a print on demand technology as
in (1) book.. Then the book gets bound and finished typically for
under 100 bucks.. It is presently solely a production go fast process. In my
process I basically proof everything.. I'd bet 1/3 of my clients wouldn't know
how to do an in gamut image even if you held a gun to their head..
I'm not that versed on the print machines that are
used but I'd honestly be curious if any have 6 channel capability that would
lend themselves to a make the book process.
I think both Light jet and Chromura technology
would work great if they could get to 2 sided printing.. Also in that instance
you could mix B&W and Color easily.. I've done a couple prototype books
using Chromura prints.
