Getting Additional Project Permissions via OData?

[JakeP]

Is it possible to get the additional permissions set on a project using the custom permissions option via OData? I need to mimic the security in a supporting application. So if the Project Owner adds an additional user to the Project Permissions, is it possible to get that via OData?

Thanks in advance, 
Jake.

Unfortunately, it is not possible to get this information, btu it would be extremely helpful if you could.

Thanks for confirming. I had my doubts.
