I have taken a similar but slightly different approach to this since 2003. I have always had a Gigabit switch in my network so I have always done it this way. However not all my systems had a video capture card so I would digitize footage on one machine and use the other for AE and editing, rendering etc while the footage lived on the other machine throughout the project.
I added two employees and two more systems and we each would upload our own projects to our own local RAID drives. We had a RAID, separate projects drive plus the System drive in each computer. Three of the four had Kona cards.
If I needed to cut one of four spots and the footage was on one of the other computers it was never an issue with our network to edit off those drives. There are a few caveats to using this method over gigabit, but currently in our new building I have 6 Mac Pro systems on the network and we constantly share media between drives. No problems editing ProRes (we do not use HQ) and it is seamless.
I believe this way makes the network more efficient than having all the footage on an Ethernet SAN and pounding that device with every computer. Seems the system likes having the footage locally if possible, and then we can connect to that computer if we need to.
With the Blackmagic Videohub we can route from our desk and all our machines and decks live in one room…the edit rooms are as far away a 80 feet and we run long cables from the server room for monitors, keyboards and sound.
This is about as DIY as you can get and it has been rock solid since 2003.
