[Ietf-caldav] Some issues with caldav - subscriptions

[Mike Douglass]

I don't think that works too well for something like free-busy. What if 
our user subscribes to our public "movies" calendar say and wants all of 
them to count as busy time? (I guess there might be a better example.)

Also, if we use multiple clients the user has to configure all clients 
the same way to see the same results. I believe calendar aggregation is 
a sufficiently useful feature that servers should (also) be doing it and 
I believe it's also the only way to get a correct free-busy result.

I understand that clients CAN do this and how. I just believe that we 
should allow servers to do it and make the appropriate accomodation in 
the protocol.
