"The .rpc library we have is 12.3 GB of stuff. Admittedly, thats not THAT much space, but i cant justify having it on the hard drives. Since our Material JPG's are on the network as well (Additional render appearance paths) if someone is trying to render at home we have issues anyway, unless their machine has configured Offline Files, which we do with the libraries when people have to work off site. Then its local, but still pathed to the network. :)"
Note: one of the nice things about the recent updates to Archvision Dashboard is that it supports license login / logout, meaning you can logout of Dashboard in the office, then go home and login again without using an extra license. This would give you access to the cloud library of RPCs, which could be downloaded and used wherever you are.
