Thanks Rüdiger, but neither of these really answer my question.

With Adobe's Acrobat Reader prior to v6, annotations could be added and
edited directly within the PDF document; with v6 and later, this remains
possible, but only if the document is encrypted, and the document author
explicitly enables the feature at the time of PDF creation.

I need to be able to support this feature for users of Reader itself.
Adobe's documentation seems to suggest that it is only possible for
documents created by their own proprietary software.  Personally, I
consider this to be an asinine restriction, and a serious regression
from Reader-5; presumably Adobe see it as a method of protecting their
market share.

Keith.
