Hi,
can someone please explain the following :
how do s/w vendors ensure that a customer who buys a CD can use it to install the s/w only on his computer and if he takes a CD dump, the second CD will be of no use to anybody else?
i guess there must be many techniques to do that but which one is used frequently?
thanks a lot..

There is no foolproof way. All methods tried so far have been cracked. I haven't seen any software that does this though. With floppies, there used to be a few sectors at specific places that were marked. If the disk didn't have these sectors, it was considered a copy. Maybe the same is done for CDs.

Hi,
Lets setup a library where members can borrow cds/books/mags. We can try for sponsorships or for a very minimum contribution @ month say 99/-. I will sponsor some linux, bsd, oracle cds & also the dotNET shows.
But this way we will be able to spread gnu/linux & bsd faster & in a better way.
Can Dr. Nagarjun, Philip, NCST or FreeOS Labs or anyother organistation /lugger take initiative in this.

The CD-Recordable FAQ at http://www.cdrfaq.org/ has some suggestions. It is surely worth a hit.

This is done for DVDs. You burn off the first few sectors of DVDs, which contain the region keys. This prevents the copy from being usable by normal DVD writers with commonmly available blank DVDs. Nothing stops a DVD pirate from obtaining a truly blank disk, and uing dd to accoomplish his goals though.

Do you still want this after listening to the RMS lecture. I am sorry if you want this for the knowledge's sake.
