we've been using Announcements in our Seaside App for years now and 
apart from beginners' problems (like not unregistering properly and 
therefor having all kinds of strange phenomena) they serve their purpose 
very well. The housekeeping of subscriptions is key, you can shoot 
yourself in the foot easily.

No. They are local to the Announcer that you use. We use our WASession 
subclass. But Seaside does nothing to make Announcements local to 
anything. Whoever subscribes to the Announcer gets Announcements. So to 
some extent you can make them local to a Session by using the Session as 
the Announcer, but still you could forcibly register subscribers that 
are outside of the Session. It is your responsibility.

Not that I know of. But that doesn't necessarily mean anything ;-)
