I only synchronise the Templates folder and the Library folder. You should be able to sync the Workspaces and Plug-Ins folder too though.
The only problem, I think, would be the notes database (which is in Plug-Ins>Common>Data>Notes), because this is the one thing that is probably conducive to being centralised (via an Alias/Shortcut) as it can then be updated and edited by everyone. Using ARD to sync it as above would mean that any edits done by other people to the database would be lost each time you propagated the master to their machines.
