Workspace Sync on Netbeans

I need to synchronize two IDEs in a project I'm developing. We are two programmers and we need to see the changes in real time, serial something like Google Docs. I remember Eclipse had a plugin that did just that, but it was discontinued. If anyone knows a plugin or some way around this in Netbeans , please help. I did not want to implement a CVS because it would involve creating a server and private GitHub is paid for.
