Squeak is still a great system but all the cool things are happening behind closed doors at the croquetproject... Ofcourse when 1.0 comes out I'll have to back-port in all of the enhancements I've made to 0.3. =\
Just curious ... what improvements have you been able to make to Jasmine?
Also, you may be interested to know that I am working on the Croquet Consortium public portal, which will, among services, provide SVN for Croquet's code and communal content after 1.0 is released, and the development model moves out of the cathederal and into the bazaar.
