- Fristly, I want to say that B&W doesn't have copy protection, nor do we have
- plans in this area at this time. I'm not going to debate how easy or
- difficult any copy protection scheme is to break. I will say that the major
- reason that a company like FTP, SUN or B&W (correct me if I'm wrong, SUN & FTP),
- is adding copy protection/notification is not to stop the hackers from
- breaking the protection and running several copies, but to make companies think
- twice about illegaly copying software. In several foreign countries, companies
- don't think twice about using a single copy of software on all their machines.
- If they require a hacker to break the protection, they would have to consider
- their actions and most likely "do the right thing".
-
- There are other countries, like Brazil, where there are no enforced copyright
- laws. What should one do in a case like this? I beleive that Microsoft won't
- sell any of it's products there anymore. They have a LARGE lawsuit against the
- brazilian government.

- It is not as simple as you are descibing. The ARP packets have a
- series of special codes which indicate that it contains an "FTP serial #".
- If another company did this, they would choose a different "special code".
- Just like ethernet address, vendors must ensure that the special codes
- are different. Maybe (I don't know) FTP uses the letters "FTP" and B&W
- might use "B&W" ... :-)

-
- As I indicated previously, B&W does not have any protection
- scheme and that we have no plans at this time to add one. I should also note
- that the pressure to add one is coming from foreign distributors in certain
- countries.
