I just had a quick look at GWT (again). It seems to be a great tool, but 
I don't know whether it would solve the rendering issues. As I 
understand it, it optimises the JavaScript code. Thereby, it eliminates 
some cross-browser incompatibilities and improves the performance of the 
code. At least the issues I was referring to, are problems of how 
different rendering engines display the SVG (whether or not there is a 
script embedded).

This is not to say, that moving to GWT is not a good idea. One worry 
that I have is that GWT is very much geared towards "web-applications" 
in the sense that it is based on HTML and focuses on solving problems 
concerning form handling and server-client communication, which are not 
a big concern to JessyInk. However, if it improves the development speed 
and can be used with SVG I am all for it. Do you have some more insight 
into or experience with GWT?

Sounds interesting. If I understand it correctly, you would suggest an 
HTML-based page that loads one or more SVG-files. I can see some 
advantages to this method, but I wonder how the workflow would change 
and how Inkscape (or another editor) could be incorporated into such a 
set-up.

Cheers,
Hannes
