Question about subscriber/subcription

[Rafa Marin Lopez]

Hi all

Could anybody point me out an very basic example about how a server can 
register and handle subscribers/subscriptions to certain events?
Also I would appreciate an example how a client can register to receive 
these signals.

Thanks in advance.
