I was thinking more in a direction of including some MIT licensed php telnet library. If I'm on the right path about this, then there is no need for installing netcat, "only" php and Apache web server. But from your examples, netcat command prompt seems pretty simple to use. I'm still not sure about php running native programs, especially receiving an output from them, including running the whole app directly from the web.
