Just a quick note about our progress. Everyone (especially me) has been really busy over the last couple of weeks, hence the low level of activity on Tangle. I have been doing some work with the scripting engine, though. We're using Lua for now, although I'd like to explore the possibility of porting the SpiderMonkey javascript engine to .Net at some point when I have time. On the other hand, I may decide that Lua handles our goals well enough to not require a change.
Also, our newest developer, Lynix, has been working on the application shell for the map editor, and has a basic system running. Well done Lynix!
