> r u kidding... IE doesnt... excanvas simulates canvas behavior in IE.Which goes back to what I said about their not being enough browser support for the effort to be worthwhile (ON PUBLIC FACING WEB SITES). If you can convince your IE users to download and install excanvas, then more power to you.
You misunderstand. It's a javascript file that you include on your page just like jQuery. It's no more "installed" than jQuery. Just fine for general public use. --Erik
