|“Copy-Control” may be a blessing in your case but I can think of a dozen exceptions to this rule.
In my previous job, a (marvellously stupid) tech writer had managed to totally mangle the protection bits of the main documentation PDF file, in such a way that copying, printing, etc… was totally disabled.
Needless to say, that was a major pain in the neck for Tech Support, Marketing and just about everyone who needed to print or quote from that fscking documentation.
I had to sort the mess out — which took me all of 5 minutes (uncheck three options and restart Distiller), but it got me thinking: I have a friend who is blind. Who has been relying more and more on the Internet for sources of information and docs.
What if the poor guy can’t use pdf2ps and ps2ascii (for instance) to read an important PDF file, just because some jerk decided his PDF file would not allow text copying? What about the idiotic tech writer mentioned above, who had no clue whatsoever and just locked every PDF file?
What I am saying is: get rid of the fscking copy control. If you post PDF file on the Internet or on any kind of public network, you are, in essence, forfeiting any copyrights you may have had — any form of protection is futile anyway, since the elite script kiddies mentioned by some other poster will crack it anyway.
