- I'd go for plan B, unless you get unreliable service from that (some
- configurations of Win3.1 don't like the LWP DLL. The problem is,
- it's difficult to find exactly what causes the problem). In that case,
- plan a becomes the fallback position. Also, there is no reason you couldn't
- have *both* available.

- Probably worse, especially if it means things get dumped onto the same
- physical cable twice.

-
- It will cause some. Some will also be caused with TCP/IP if
- the server is also a bridge or a router.

-
- There shouldn't be. *This* is a Sybase question. Presumably it's just a
- matter of specifying both in an interfaces file.
