We have tried this approach on the NLnet backbone machine (hp4nl)
running HP-UX 7.0.
However, there remain 2 problems with it:

1. The t-protocol, which is the best one to use for UUCP over TCP/IP
   (and is specially designed for that) is not supported by the Hp
   UUCP implementation.
2. The f-protocol (meant for UUCP over X.25), which is chosen in
   some cases as second best, contains a very old bug (it does not
   check whether stdin is a tty, before doing an ioctl in the routine
   fturnon in fio.c, as is done everywhere else in the code).
   This bug causes uucico to abort with:
    "ASSERT STTY FAILED".

With Sun's on the other side it works (Sun choses the g-proto, not
very efficient though, to say it mildly). With many other UUCP
implementation one runs into problem 2).

We had the choice of running our own UUCP version or to get rid
of the UUCP over TCP/IP connnection with non-Sun's.
We did the former previously, but resorted to the latter later.
However, I must say that we never could have done that without
the friendly cooperation of the EUnet backbone (mcsun), who took
over our UUCP over TCP connections.

Regards,
