The best solution I have seen to date for multi-spectral imaging is
the one Megavision (http://www.mega-vision.com) showed at Photokina.
This solution uses a monochrome camera with special LED lighting
instead of color filters to achieve the channel separations. The
solution is much faster than the scanning approach taken in the
Lumiere JumboScan. The Megavision approach also avoids many of the
optical issues encountered with the spectral filter systems.

Really? Nothing from Sinar? How about this system:

I heard it was used a few years ago to capture the Mona Lisa by the
Louvres
museum because they were afraid that something bad would happen to
it.

No, nothing from Sinar.
I am familiar with the Lumiere camera system and I've met the person
who
designed it. As far as I understand, they had difficulty actually
selling
the camera to anyone (there is only one system in place that I am
aware of,
although I don't think it was ever actually for sale—they want to
lease) and
now they just offer spectral photography services.
Besides, for reasons I won't go into on this list (too out of
scope), there
are some issues with actually using that camera system in a
practical way.
It's NOT a system for high production. If you don't have time to
make some
local color corrections, then you won't have time to capture a
painting with
this camera.
Feel free to contact me off-list if you want to discuss this further.
