The following much simpler code works in Safari (with a WebKit  
nightly, that's the only versions with SVG support so far) Opera 9  
and Firefox 1.5:

I don't have Win IE + ASV to test with but I suspect it would work  
there too.

This relies on three things that are not currently standardized:

1) contentWindow property of the <object> and <iframe> elements in HTML
2) frameElement property of the global object
3) parent property of the global object

But I think all three are interoperably implemented in major UAs.

The CDR proposed document.referencingElement would replace the need  
for 2.

referencingElement + contentDocument could replace the need for 1 if  
you attached the functions to the document instead of the global object.
