Fitzoid,
I believe I tried pdf995 and pdf995edit before, as well as some other PDF tools, and it turned out not to be 100% compatible with Adobe Acrobat. One thing we use Acrobat for is for drafting and commenting on various standards committees I work on. Seems that I recall it didn't work for that, but I will check it out again.
Regarding Illustrator. I suppose it comes under the never know when it could come in handy section. <g>
Thanks,
