This would be extremely valuable. I actually tried to do this myself with Acrobat 5, but it doesn't import PNGs which are used throughout the SDK. Very frustrating to say the least. I would truly appreciate a printable copy of the docs.

We are working on converting the documentation to a new format. We will write the docs in eZ publish native format and export to other formats later. This will be ready in time for the 3.1 release.
We will make genral XML exports from eZ publish in future releases. This will then be used on the docs, so we will probably release the docs in several formats.
