When a client gains access to a server model some handshaking must be done.
During this handshaking process, the client's version is compared to the
server's version. If the client's view is out of date then any new
items added to the server model since last clients access are downloaded
prior to interaction.
PRO: All clients see the same model of the server
PRO: Reduced server impact, especially if models close to static
CON: Language must incorporate histories of updating and version control
