My code is alpha so use at your own risk.
This automagically installs dependencies and compiles sqlite bindings
To run the webserver:
connect to http://localhost:8080/tweets
If you enter a message in the box and press 'send', it will send your message to every other server on the entire network.
To send a message to all webservers from command line:
node client.js "Some interesting message"
The messages from client.js will propagate to every webserver in the network.
It's routed using the Telehash distributed p2p network http://www.telehash.org
I also included a php client:
php client.php "Some interesting message"
