DeepFreeze vs. Network Home Directories?

Outside of perhaps saving a browser’s bookmarks, is there any drawbacks to using Feronics Deep Freeze for OS X with a local user that has to connect to a server to save docs vs. having users connect to a file server to get their home directory to save docs. I am just wondering if the Feronics Deep Freeze with a managed local user is more streamlined and easier than having all of the network home directories business. I just think there could be easier ways to doing multi-user environments… what do you all think?
