Not to forget our highly nerdy team of programmers that will help give JavaScript an even bigger push by allowing JS deveopers to built whole apps within a desktop just using JavaScript, including file management, window management, user management.. all you need, open sourced, install on your own hardware or run somewhere else. Client side encryption and DOS drivers to allow integration of arbitrary datasources included. disclaimer: I am part of that team :)
