Hi Hans,

There is capability in the module to achieve this, whether it scales to your needs is another matter. You can use the modules permissions to restrict a single intsnace of the module to a group of users. This can be done across multiple module instances. So Group A is set up for Module A, Group B for Module B and so on.

Assuming you want all these to be displayed via one calendar (Module Z) on your home page for example, then make Module A,B,etc sub-calendars to Module X. This is done via module settings, in the sub-calendars section. If you are using Events 5.x, this will observe your security set up on the sub-calendars and only display eventys the user is entitled to see.

Cheers
Roger
