I have yet to get my brother 8860DN working properly, but it seemed to scan fairly quickly when it was working. I am about to return it for the second time.
It is probably sufficient for what you need for scanning. You really ultimately only need to control it by one machine, although the ability to fax from multiple machines would be nice if I can get that to work.
Again, I have only had mine for 3 months and it has not functioned well for 2 of the 3 months. I also have a fujitsu.
It is fine to network, but you need to be near the scanner to put the documents in the feeder. Thus, really only one machine really needs to be near the scanner.
