I would be interested to know what you think about my web service 
framework so far[0]. Blog post about why I did it here[1]. I was 
trying to sort our UI issues with DOOGLE[2]. But the latest talk 
about a new UI system basically killed my want to work on it 
altogether. It would have enabled building a GUI app and then 
very simply building it for a web as well. Without changing much 
code. Don't think any GUI toolkit exists that can do that.
