Michael, Thank you for the response. What I am doing right now is forwarding the packets from the tunnel.py to a JMS (Java Message Service) server using the STOMP (http://stomp.codehaus.org/) protocol, available for python. JMS server is pushing packets from its clients to the tunnel.py. What JMS gives me is the asynchronous message-based communication and reliability. The JMS server can talk to clients written in a variety of languages (Java, C, C++, C#, Ruby, Perl, Python, PHP). At this point the only issue is that I forward packets from the PHY/MAC layer almost directly to the application layer.. I guess using the TUN/TAP would forward packets through the kernel's network stack and provide implementation of the higher levels of the OSI model, so I wouldn't have to worry about things like lost packets and segmentation..
