    You can get the image data from the context of the canvas. Like this:

    var w = 400;//width of movieclip

    var h = 300;//height of movieclip

    var l = 100;//left of movieclip

    var t = 50;//top of movieclip

    var ctx = canvas.getContext('2d');

    var imagedata = ctx.getImageData(l,t,w,h));

    Sending raw image data sounds rather bandwidth-unfriendly. Note that you can have the browser convert canvas data to compressed image data for you automatically.

    Would that easily allow you to only send the area of a particular movieclip. or would you expect server side code to do that extraction?
