POE and it's filter framework make it ideal for protocol implementation. As many protocols do, they are simply payloads layered like an onion. By implementing filters for each layer and stacking them, it enables a clean, and encapsulated way for developers to get to the core payload without cluttering the guts of the application with layer stripping code. A prime example is XMLRPC. This is a dissection of the filters needed to successfully implement an XMLRPC server/client.
