Caldera 9.x and FC8000 on my setup.
Network did not work for me.. It works for short jobs but when I had a longer cut job, it would stop part-way. Very hard to figure out what was the issue. Caldera support just shrugged their shoulders. I don't think it was a problem with the network, as we do also use the Cutting Master plugin in Illustrator and it runs flawless over the network, even with really long cut jobs (real intricate stuff that takes 15+ minutes to cut).
I gave up and just got a long USB cable to make it work with Caldera. I still have it hooked up with ethernet as well so another computer can send cut jobs through Cutting Master.
Hope it works for you, but if you run into problems, you might want to look into the job length and see if you have the same issue.
