Awesome UNIX utility!
I had written a small program, named sockio, which does a (very) small subset of what this awesome socat utility does. When I discovered socat, I was impressed by the number of useful features, in particular SSL support.
With its clean design, this utility keeps the spirit of UNIX: Basic utilities that can be piped or connected together!
The possibilities are infinite. I can now connect together any two bi-directional streams.
Now, I'm tempted to write a Windows port.
