Ok, so does anyone know if there is a possibility to redirect the packet
driver's packets to another IP stack temporarily?  This problem can't be
rediscovered very seldom, I think, so maybe someone solved it before?
A possible way would be to have a 'push' & 'pop' executables, who operated
on a registration stack.  Only the registration on top of the stack would
get the IP packets.  Then one could have a .bat file saying something like:

push IP
telbin
pop IP

when one wanted to start telbin, and PC/NFS had control over the packetdriver.
Of course NFS wouldn't be accessible from within telbin.  How does this sound?
