- As the evil person who coded the first of these serial number
- broadcasting schemes, let me add a couple of words. First, as B&W and
- FTP have stated, the pressure from overseas distributors to retain/
- introduce such a mechanism is overwhelming. In view of the fact that
- around 50% of our sales are outside the US, this is something that we
- (SunSelect) cannot ignore. Although the situation is better in the US,
- it would be naive (and costly) to assume that software license
- violation does not take place here too. I used to be in favour of
- eliminating serialization from PC-NFS, but real-world data which we
- have gathered over the years convinced me some time ago that it would
- be really dumb to do so.
-
- Over the years, our customers have come up with extremely ingenious
- (and often amazing) ways to rework the licensing model into something
- that is easier to live with. One site blew the serial number into a
- boot PROM on each PC and ran a little program to patch the number into
- the local copy of PCNFS.SYS. Another customer with many thousands of
- PCs worldwide built their own RPC-based installation mechanism: they
- reserve one PC-NFS serial for use in their "setup diskettes", of which
- they have many copies. Booting off this diskette runs a program which
- NFS mounts the master distribution area, copies down an up-to-date
- distribution kit, requests a new serial number and IP address, patches
- everything up, and restarts with the new, legal serial. We are
- completely happy for people to do stuff like this: as long as they
- conform to the spirit of the license (one actively used copy, one
- serial number), they are free to use any mechanism they choose
- to implement it.
-
- Obviously the biggest problem with serial numbers is managing them, and
- ensuring that you don't have valuable resources (licenses) going to
- waste because they are tied to unused (or even defunct) systems.
- Customers such as those mentioned above have created mechanisms to
- track and manage licenses. Over time we hope to synthesize a generally
- usable solution from these and other techniques.
