Is there any serious implementation of applications (e.g., FTP, HTTP,
...) using this interface? Or it is just a possibility, but nobody
ever implemented full-fledged applications based on it?
Is the establishment of the connection at the execution a command like this
`exec 3<>/dev/tcp/www.google.com/80`
How to close this bidirectional connection?
