There are two
other routes to TCP/IP on a PDP11 without split I/D:
...
DCEC's adaptation of the Wingfield TCP/IP library, designed to work
with V6. It is mostly a user space daemon, but requires some kernel
enhancements.
I wonder what the performance would be like, since the TCP is in a user
process (a different one from the application), i.e. there's a process switch
every time the application goes to send or receive data. This wouldn't have
been such an issue when the code was written, since ARPANet-type networks
were not very fast, but with a better network, it would have been limiting.
