(And yes, if you caught it, it's a bad pun on the w3c @ w3c.org, the Internet standards organization.)
W3SEA is a new Systems Engineering Architecture (with an alternate, equally valid meaning 'Science and Engineering Architecture'.) Written in C++. It is designed to maximize re-use of a "unit of function". It also has a robust signaling system.
The W3SEA can interface with preexisting systems, such as Apache, Asterisk, PJSIP, and various SMTP, OMTP, and IMAP services, or it can completely replace them.
The ultimate goal is to replace them.
W3SEA can be used in different domains. It should do very well in protocol, simulation, signal analysis, data mining, distributed systems, robotics, and artificial intelligence.
