Nice work. That looks like the good starting point for serious device 

It's kind of a "software router". You specify set of rules and the 
device routes messages according to the rules.

Many use cases come to mind:

1. Device in the middle of the network switching messages between apps.
2. Local IPC daemon to let applications on the same box communicate, 
kind of like the D-Bus daemon.
3. Device at the edge of the network (say in router) broadcasting data 
from the outside to the internal network.


Btw, I believe implementing socket options is crucial atm. Without them 
it'll be hard to use it in real-world deployments.
