I do this. Don't know if it is officially supported, but it works. Since files like names.nsf and bookmark.nsf are passed around between workstations, keep in mind that you can end up with something like a local names.nsf built on a v9 template being used on a v8.5 client, or vice-versa. Hasn't caused any problems that we have noticed so far. Also, it seems theoretically possible that you could get in trouble with ODS versions of these files, but that hasn't happened to us.
good luck!
