 Yes. But this has its own set of problems and limitations. It can be a
 good tool, but only for its special set of applications. 
 
 That said, this is clearly the future for small microcomputers, offloading
 the TCP overhead to a separate dedicated device. Commodore NICs are moving
 from Crystal 8900-type (RRNet) to Wiznet-type devices, for example. 
 
   In cases like the PDP-11, though, IP isn't necessarily the protocol
of choice.
