Yes, we are experimenting with two products at Boston University:
WISCNET from University of Wisconsin (available via IBM I believe)
which uses a DACU (Device Access Control Unit: attaches together a
piece of DD11-CK Unibus backplane and a bus and tag channel into
which you plug an interlan board, it has an IBM/PC for 'control'.)
We are also playing with another implementation of TCP/IP from
Spartacus (Cambridge, MA) which has their own (K200) box for attaching
and ethernet to an IBM channel.

The WiscNet seems to be quite good, we get a *lot* of use around campus
from their SMTP. File transfers seem to be limited in speed by the
remote machines (eg. VAX->IBM is about the same or better than VAX->VAX)

We haven't enough experience yet with Spartacus to comment tho I hear
it's good (glak, for another reason we have a hacked VM and its slowing
down installation...our fault.)

This is all on an IBM3081, but 43x1's are a more typical configuration.
