- Marketing ain't the big fundamental problem here people. The
- fundamental problems are 1) cost and 2) interoperability. I've got
- lots of OSI products that have passed "Conformance Testing" and have
- COS certificates -- but independent implementations still don't talk
- to each other. Until they do talk with each other, it isn't solving
- my network problem. Also, I get TCP/IP and friends at no incremental
- cost with my OS. I have to pay significant extra chunks of money to
- get OSI. There is no reason to pay more given that TCP/IP and friends
- work fine and are interoperable today off the shelf.

- Wrong !

- I am a former employee of one of the firms you cited and I can tell
- you that the ONLY reason that those firms implemented MAP and MMS is
- that General Motors made it a procurement requirement and GM is the
- largest purchaser of real-time controls in the world. What you wrote
- just ain't true.
