NodeType Visible to its defined Site/Package

Hello All.

Is it possible to show the NodeType only those defined in its own package.
Currently I can See all the Nodetype defined in all project for every site.

Please help me here

To achieve this you basically have to define a separate nodetype structure for both sites starting from the homepage. So define some abstract base types that you want to reuse on both sites and then the real nodetypes that just inherit from them but might have different constraints.
