==========================================================================
 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.

 Multiple recordings
=====================
Definitions:
Camera
	Decoder - "input" (global)
	Transmitter - "network connection" (one pr. session)
		Buffer
	Player - "output" (global)

Implementations:
Camera {
	set active transmitter to NULL
	start decoder
	start player
}

Camera::start(cpr) {
	start transmitter
	set active transmitter to the new transmitter
}

Camera::stop {
	tell transmitter that the last frame has been read
	set active transmitter to NULL
}


Decoder {
	while(!done) {
		read frame
		push it to the player
		push it to the active transmitter
	}
}

Transmitter(cpr) {
	connect
	while(!last frame read && !queue empty) {
		send frame over the network
	}
	disconnect
}

Player {
	while(!done) {
		show frame
	}
}

Frame {
	properties:
		flags; (FREEZE, SNAPSHOT, SAVESTATE)
}
