this is a nice introducing.

I've looked at it, but I don't think it solves the problem. We need stream-based handling with thousands of connections. Mina's stream io handler requires a separate thread per connection:

So mina doesn't appear to solve this problem.

I know you are trying to stay as much as possible independent from third party libraries, but may
but mina looks very interesting from my point of view.

I'm not afraid of 3rd party libraries. Mina did not exist when I wrote Nutch's IPC code. If someone would like to re-write this using Mina, and it uses less code and runs as fast, then I'd be happy to use it.
