Yesterday the first organized DENG developer chat (log) took place. DENG, if you don't remember, is renders large subsets of XHTML, XForms, SVG, SMIL and other formats, styled by CSS2 and 3, written in pure Flash/ActionScript.
Besides the active developers and some interested thirds, M. Dubinko (XForms Essentials and S. Pemberton (Chair of the W3C XForms WG) took part in the conversation.
I learnt from the chat log that they don't compile the software with the expensive Macromedia Flash environment, but with KineticFusion (free download, closed source, still interesting).
They were pondering a couple of options on how to proceed with the development, pointing out a standard-compliant DOM implementation and an fitting XML event engine as the issues on top of their list.
As ActionScript itself is basically standardized ECMAScript (like JavaScript), it seems to be a promising and rather probable option for DENG to switch entirely to ECMAScript, gaining even more flexibility in deployment. (!)

DENG Chat is taking place every 1st and 3rd thursday of the month, second time on July 15th, 18:00 CEST on #codeazur (irc.freenode.net).
