The concept of private VI's

[Anu Kalidas]

I liked the concept of Private VIs that can be defined in a project file. Can use it to implement goop more effectively..

Yep - in fact, it's not limited to OO: you can make any VI in a group private to another public VI, meaning that if you drag a private VI from one group onto a VI that's not allowed to access it, the run button will break.
