I think Syan has an excellent point, and I remember we discussed this already 
a year ago.

I would propose the client stores it's state in an XML file of the format
<path>
author/location/timestamp/server
        <module>
                <widget>
                </widget>
        </module>
</path>
This file is erased when the client exists cleanly.
When a client starts up, it checks whether a file with
<user>.gnumed.xml exists
If so, it checks if it has connected to the same server (from path statement)
If so, it asks the user whether it wants to retore state

During usage, every widget has a "save_state" method, which should be
triggered by a "on_timer" method as well as a "on_backend_failure" and a 
"on_crash"
