SAVE THE MOVIE?
==========================================================================
When the stop button is clicked, a msg box pops up, "Save? [yes, no, dunno]"
network connection is no killed before this has been answered, and an empty
frame has been send to the server with the answer.
On the serverside, a variable describing wether the file is to be saved (SAVE),
deleted (DELETE), og scheduled for later descision (LATER).
It is initialized with LATER, in order to prevent errors due to a malfunction
leading to a disconnection.
If a flag is recieved, the state is overwritten.
If the state is SAVE, when the connection is terminated, the file is moved to
a folder containing permanent data store.
If the state is DELETE, the file is moved to a folder containing files scheduled
for deletion, when more space is needed (no files are removed at this point)
If the state is LATER, the file is moved to a folder containing files with this
purpose.
A cron job examines this folder regularly (test how often).
If a file has been here for more than a week, the administrator is contacted by
email.
