Drawing API and interactivity

Question

I am about to start this project where the background on a
full browser flash site has a number of shapes. Ideally and I am
not sure if this is even realistic, I would like the shapes to have
a slight mouse interaction. While the mouse will respond to button
etc in the front, behind the content, on the background, it should
create slight interaction, such as slight wobbles of the shapes
there, slight nudges, etc.
I have used the drawing API for simple things, but I am
wondering how hard it is to create some more organic shapes. Can I
have circles that have slight dents in them? Bows? How hard is
that?

use the jpegencoder class to encode your jpeg and the urlloader class to send to your asp.  eg, to save mc:
import JPEGEncoder;
var bmpd:BitmapData=new BitmapData(mc.width,mc.height);
bmpd.draw(mc);
var jpegEnc:JPEGEncoder =  new JPEGEncoder(75);
var jpegDat:ByteArray = jpegEnc.encode(bmpd);
var ldr:URLLoader=new URLLoader();
var header:URLRequestHeader = new URLRequestHeader ("Content-type", "application/octet-stream");
    var url:URLRequest = new URLRequest ("youraspfile.asp?name=snapshot.jpg");
    url.requestHeaders.push(header);
    url.method = URLRequestMethod.POST;
    url.data = jpegDat;
    ldr.load(url);
in php the image data is
$GLOBALS["HTTP_RAW_POST_DATA"];
so you'll need to translate that to asp and save it to a file named by the name variable sent via GET.
