how to write Factory Interface Handlers

Hi,

         Anybody knows how to write factory interface handler that will call multiple handlers. I'm using Sharepoint Services in my application. In this sharepoint i can able to add only one event handler. But i'm in situation that my sharepoint has to communicate with multiple event handlers. I asked this question in Sharepoint forums. They suggested that "You can write a factory interface handler that calls multiple handlers. " . But i didn't get any suggestion about factory interface handler from them.


     If anybody knows how to write factory interface handler that will call multiple handlers.

Thanks in advance,
Vinoth
