Thanks, Sam for kicking this off - I knew it was just a matter of time before someone would do a proof-of-concept, but the week of MIX07 was earlier than I expected! 
One suggestion: If you’re going to use simple IE detection, then why not use IE conditional comments rather than forcing other SVG-capable browsers to load and parse and run the JavaScript? Something like:
<!--[if IE]> <script type="text/javascript" src="SVG2SL.js"></script> <![endif]-->
The problem is that IE conditional comments are ignored by other browsers, meaning that that script will always be included.
If all goes well, I’ll likely use a technique such as the following:

Actually, Sam, the script will NEVER be included in other browsers (the whole thing looks like a comment to any browser but IE).
