I've been writing asio apps for a closed-source software company for the 
last 16 months.  With asio, I've written:

* a custom HTTP proxy that has been running in production non-stop since 
October last year
* an HTTP<->XMPP gateway
* a simple asio-based HTTP load test tool (so I can simulate 20,000 
simultaneous HTTP "clients" from a single process)
* a publish/subscribe server with a simple binary protocol- am still trying 
to performance tune other code so I can find the limits of this, so far 500 
messages/sec doesn't cause any detectable CPU usage on a 3GHz P4.
* A second custom HTTP proxy- this one does some authentication as well.

The first application runs on Windows and the rest run on Debian Linux.  
They all share HTTP/networking code where applicable. All applications use 
boost::bind and boost::shared_ptr extensively and the publish/subscribe 
server uses boost::regex to figure out how to route requests.

I am addicted to asio.  I can't stop using it ;-).
