Hi m0ms3c,
I have done some work to look into your previous question regarding creating specific permission profiles using Role objects. I have some progress but I have not found time to present the solution into a formatted answer yet.
However, it appears you have also achieved some progress. Can you describe your current setup for sharing resource permissions among users so I can share your vantage point. There may be more than one possible way to accomplish what you are doing and I want to ensure that readers of this question can be on the same page as you.
