SilkJS, a synchronous JavaScript shell using V8
http://silkjs.org/
- Probably meant to post the link, so here it is: 
- SilkJS includes a lot of libraries that have different licenses. The idea is to allow anyone to download and use SilkJS and live up to those licenses as they see fit. - If you want to sell SilkJS, you have to pay Oracle a license fee because SilkJS uses libmysql. - Make sense? 
- I've never seen software with a 'Pick whichever license, as long as it's OSS' licensing before. - I'm not really sure what the implications are, but it could make things hairy if people are releasing modules or extensions to this that use various licenses. 
- The site looks good, but a few prominent TLDR use cases and/or call-to-actions would be useful. - I already use Linux and am not sure how I would use this, and am too brain-tired at the end of a long day to dig into the site and figure it out.
