I've solved the first problem in the series of those caused by  
FireFox's native SVG implementation. Following your lead, I found that  
substituting "svgDocument" with "document" makes SVG better behaved in  
FireFox's SVG implementation, and still works with Adobe's plugin.
The next problem is harder to diagnose. The image viewer now loads, but  
without the widget windows. The javascript console says:
Error: uncaught exception: [Exception... "Component returned failure  
code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMSVGLocatable.getBBox]"   
nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame ::  
http://localhost/JavaScript/SVGviewer/stats.js :: anonymous :: line 70"  
  data: no]

There haven't been any discussions like that recently, but it would  
certainly be possible. Limitations of html are ability to zoom, pan,  
and easily draw overlays. Still, a stripped down html/ajax viewer would  
be useful. There was one three years ago, but was depricated in favor  
of the SVG viewer. If it were resurrected or cast anew, we could easily  
have the preferred viewer be a system preference. The old viewer can be  
found here:
http://cvs.openmicroscopy.org.uk/horde/chora/browse.php? 
sa=1&f=%2FOME%2Fsrc%2Fperl2%2FOME%2F
The files to look for are: GetGraphics.pl, GetGraphics.pm, and the  
Graphics directory

It may be easier to write it from scratch. Much of its functionality is  
pre-image server. The image server's composite methods do most of the  
work now-a-days:
