The packet drivers allow you (under some conditions) to run two
different protocol stacks simultaneously. They do not provide a means
for running two stacks of the _same_ protocol simultaneously. This is
due to the way demultiplexing works. The packet drivers sort packets
by type, sending those for Protocol A to the Protocol A stack, and
those for Protocol B to the Protocol B Stack.  If both stacks are the
same protocol (in this case TCP/IP) this will not work. Also, if both
stacks are the same protocol, both will need to receive broadcast
packets.  You will not be able to get a TCP/IP & NFS package that will
coexist with NCSA Telnet.
