Deploying Network Services behind Corporate Firewalls: Net.TCP Port Sharing in WCF
Just found a good feature of WCF, which seems quiet useful for distributed application developing/deployment practices. Through Net.TCP Port Sharing Service, Windows Communication Foundation (WCF) allows different processes to share the same TCP Ports. Now you can deploy your .Net based network services side-by-side with IIS on port 80 or 8080, the standard HTTP and HTTP Proxy ports you find open in many firewalls by default. No need to mess around with client’s network department on this one. 
Read on at MSDN: Net.TCP Port Sharing, and don’t forget to read the related articles on enabling and configuring the Port Sharing Service.
