Open Source and Javascript

mr_burns asks: "I was wondering what people's opinions were about GPLing or otherwise OSS licensing javascript code. I have some pretty cool code I want to share with everybody, but I don't want to be screwed. I look forward to establishing a method of collaboration such that we can all take ECMA-262/javascript to the next level. Why should Slashdot and other DB driven sites rely on a servers processing power when the client machine is mostly idle? I think colaboration between client side and server side scripters in an OSS context could make things much more efficient. What pointers do the OSS community have that could guide the way, and what are your opinions on the matter? Thanks in advance for any feedback y'all can give." What do you all think? Is Javascript robust enough for this sort of thing?
