My only objection is that I have similar read >functions in both the server and the client application. So, the Admin tells the server which db is the Live one? If a client then asks the server for a non-Live db, then the server would disallow writes. So, instead of checking "is connected", check "is Live db". Does your server keep session info per client? It could set a flag at the db_open event : Live or Archive.
