are available from many places for the cost of copying them. However,
they do not come with support.

Support for the packet drivers is available from Crynwr Software for
US$100 per year per type of driver per fifty users.  Site licenses
are cheaper, please contact Crynwr Software for a price quote.

networking software that you will be using.  Terms of the support are
available on request.
