Not guarenteed, but I did see some information (from SCO I think) saying that DLC/NetBEUI would be supported on SCO's LM/X full release. This is not exactly the world's most popular protocol set, but it is the one used by IBM/Microsoft for LAN Manager, and is supported under 3+ Open (until 1.1 dies, probably later this year). It may not be as memory efficient as NBP, but it is small and fast relative to say TCP/IP or XNS (IMHO), and its penetration into the PC LAN marketplace does mean that it is reasonably well placed for interoperability requirements. It also has the advantage over NBP of supporting routing, which is increasingly being viewed as important given the number of WANs in the modern world. The best thing as far as I am concerned would be flexible routing of ESMB packets across transmission protocols, so that given a TCP/IP based LM/X net on one side of the corporate IT structure, and DLC/NetBEUI on LAN Manager on the other, one could route through a single machine if necessary, reducing the need to either standardise on one protocol only, or make every machine multi-protocol. Obviously, there are many structures which require the flexibility of multiple support, but a choice would be nice. Ah well.
