I did exactly what you suggested. I purchased one of the SCSI-Ethernet adapters designed for use in the Mac and tried it under Fusion. When I had the device I had checked around and some people said they got it working but I was never able to.
The further complicate things, the drivers are not compatible with OS 8.x or greater on the Mac. I don't know if you know anything about Macs but if you do you will know that networking on a pre 8.x machine is a nightmare.
I wish you luck. It may have just been my machine in the end. As I did have quite a few problems with it. Let me know what you think.
