Ethernet would speed up data transfer between the server and the
workstation as well as be able to handle much more traffic. In this
case I don't think the net would be the bottleneck, the server would
(provided the net is designed properly).

PLUG: The piece I did on enhanced LocalTalk in the October issue
should also give you a bit more food for thought as far as which net
to go with.

Hope this helps.
