I think there is third problem here: where providers can get
requested information from?
I mean: Dispatcher has loaded a provider and ask it "how many users
are connected to you"? What should the provide do?
a) Should it keep list of connections in some kind of internal
provider-global cache? No! Too ugly.
b) Should it onestly answer "I don't know"? No. It is useless.
c) ???

Providers don't have enough information for answerring
fb_engine_info() calls. Only server has. But even server can be wrong
(consider Classic mode for example).
I'm afraid there is no good way to support this call and keep fine
engine granularity/layering.
