Photoshop CS4 supports separations using N-channel ICC profiles up to 8 channels.
Then I may have misunderstood something.
And little wonder, because quite frankly some of the stuff at the FOGRA-symposia may well go over my head.
As I don’t have any such profiles myself I can’t test the feature, so allow me to ask a follow-up-question:
How does this relate to Layers – can one work on (up to) 8-channel Layers and would this include Adjustment Layers-capabilities and did I just miss this?
(And if not is such a feature likely to be included at some point in time in Photoshop?)
We don't support N-channel layers.
The support we need for N-channel preview and interaction is still not ready for prime time (internal code and external profile wise).
Also, changing to support an arbitrary number of channels of color data will require a huge number of changes to the application to make even common features work -- something we're not likely to undertake without a demonstrated real-world benefit. (and frankly, I can name only 30 people worldwide who really need to work in multichannel/multispectral mode at this time).
We just support separating documents using N-channel profiles (by far the most common use).
Thanks for Your answers.

But it would seem that this may be a solution to certain dissatisfactions with the Spot Channels’ behaviour that have come up in this Forum, too.
Well, not a straightforward solution, I guess, as one may not want to separate an image using the additional Channels but keep that in CMY(K) and only use the Spots for graphic elements etc. … and if Photoshop were to provide seven-Channels-Layers I suspect it wouldn’t be long until someone asks for eight.
The packaging-industry’s needs don’t seem to be met by the CS currently, but the cost-benefit-considerations are certainly valid.
It might be A solution, but how much work is it to support the needs of relatively few people?
The Packaging industry mostly needs separations and some spot touch up -- which can be done in Photoshop CS4.
If the packaging industry would explain their needs (not wants), we'll see what else we can do.
But yes, there are huge cost-benefit tradeoffs.
