News Calander which works with permissions

The Problem:


I have tried several different modules which will give you a calander with which to view news items for a specific date. However, I have permissions set on the site so that certain groups can only see the news topic which relate to them. When I install the calanders, which are basically a news sorting module, they ignore the global permissions and suddenly everyone can see everyone else's topics.

What I Need:


--A calander which sorts news items into the appropriate day, month, ect.
--It needs to work with topic or category permissions so that groups only see their topics.

Does something like this exist anywhere?

Is there a way I can work an un-modded PN.726 to handle this?
just set topics permissions to different user groups and query the date from the database
PostCalendar...

And if you are using un-modded PN 726, you should upgrade to PN 750 or 760.
