Judging by your description, the trainers don't need to alter the text, but
simply like to strip out parts that aren't relevant to their needs. Acrobat
Exchange can easily handle that, and you could continue using PDF. Exchange
has commands for deleting or excerpting groups of pages. Extensive notes
can also be added at any point in the PDF file. When a note is not in view,
it appears as an icon on the page.
