Per User views calendar listing all events for users in multiple groups

Hello,

I am also posting this in the og project, I was not sure which way to go. I was hoping someone could assist me in setting up a per user event calendar that would list all events they would have access to, since most our users will be subscribed to multiple og groups. I have a public event calendar, a organization member event calendar, and a calendar view for og groups with group specific events. On the og event calendar I have filtered it to "posts in current group", but how would I build a calendar view that could function in and outside of groups to give users access to all the events they access to on one calendar view (private og events for all groups they are subscribed to, member events if they are an org member, and public events). I am sure there is a simple way to do this, but am not sure how. Any suggestions would be great. It just seems it would be a bit confusing to users with multiple group subscriptions to not have access to a "full" calendar view with all their events in one place.

Thanks so much!
