boost::asio

The more I play with boost, the more impressed I am by it. Lately I've been experimenting with boost::asio. I have a fair amount of experience with Apache MINA for Java, and after playing with boost::asio I think I've found its rough equivalent in c++.

Here is the code I've been playing with, an implementation of a TCP proxy (accept connections from 1 to N endpoints, forward them to some remote endpoint). This implementation uses asynchronous operations for all I/O socket operations, and allows for multi-threading - by default it creates a thread pool sized by the number of hardware threads the machine supports.
