The math is still the same though.  Let's say you add a ENC28J60, the
transformers, the few required glue parts, and maybe increase the PIC to
handle the extra code and cycles.  That might add $10 to the parts cost
compared to not having ethernet connectivity.  At 100 units that's a total
additional cost of $1000.

Now how much engineering time will it take to do the extra electronic
design, layout, and testing?  Then add the time to integrate the TCP/IP
stack into your application, rework the application to a cooperative task
model if necessary, and add the new application parts specific to network
communications.  Don't forget the extra testing time.  Networking bugs can
be particularly difficult to track down.  Now add the extra documentation
and customer support time.  Network capability provides lots of ways for
customers to mess things up.  Don't you think all this will add up to
substantially more than $1000?
