Essentially, we run the same code on the server side as we do on the client side in order to unarchive the objects that get archived on the client, and then operate on them. For example, when you hit "export", the presentation is archived, sent over the wire, unarchived (using the same exact model code), then converted to PPT or whatever. You could also for example make an entire UI in code on the server, complete with connections to abstract objects, then send that entire object graph over the wire and show it on the client.
