I was navigating webpage.
I've seen some tool like git or svn , http://www.plasticscm.com/ , maybe youtrack developers may care about this....
you may add feature like this on youtrack or any other thing?
Another thing is git repository is not encrypted.
Can you make special git commercial , that will encrypt codes on serverside.
Client will have key and decode codes at runtime on IntelliJ IDE.
Developers needs more security for source code protection....
