Does anyone remember any other implementations?

The EUUG distributed it's own version, mainly written/maintained
by Piet Beertema.  It introduced the f-protocol.

AT&T shipped an (expensive) commercial version mainly based on
HeneyDanBer.  (Maybe just a different packaged version of that).

Maybe its the same one, but I remeber a special UUCP protocol which had its
MTU and timeouts carefully adjusted to get the best performance across X25.

Camtec pads and JANET anyone?
