As you may or may not know, Adobe's Image Ready support ZIP compressed TIFFs (reading and writing), but they use a different tag for the compression scheme.

If that's the case, then it's also true for other Adobe products (Photoshop, ImageStyler, InDesign, etc.) since they all use the same technology (and shared libraries) for doing image processing.

So it lloks like Adobe is already heading torwards adding ZIP compression to the TIFF specification, but is using a different tag scheme.

I don't know any of the specifics of what they are doing, but I do know that Adobe has been working on a TIFF 7, that incorporates a number of improvements.

I belive that Leonard Rosenthal (of Adobe) is on this list and could answer this question.

I am on the list, but I don't work for Adobe anymore...
