Create a stdin/stdout pipe easily over wifi or internet.

The magic part is that the program will find the other person over the local network or even the internet automatically, without needing to exchange IP addresses, based on a topic string. Just a direct pipe to another peer.

In one terminal:

$ airpipe testshare

In another terminal:

$ echo "hello from another terminal" | airpipe testshare

In this example, testshare is the topic string that each peer uses to find the other. Anybody else online using the same topic string will also connect though, so choose something unlikely to collide with other users' use.

You can generate a random topic string (on POSIX systems like Linux, BSD, MacOS) with

$ xxd -ps -g 0 -l 12 /dev/urandom
166c3e056808ed18b5d8515a

on one side:

$ airpipe topic < file.tar.gz

and on the other:

$ airpipe topic > file.tar.gz

$ airpipe free-music < song.mp3

In the terminal to share:

$ script -f /tmp/log

and in another terminal:

$ tail -F /tmp/log | airpipe my-terminal

and then on the remote side just type

airpipe

This is actually what airpipe does by default!

$ airpipe hello-ken
hey, how goes?
good thanks making some vegan pizza
ooo rad

$ arecord -f cd | airpipe chat | aplay -f cd

you could also use lower quality audio for slower connections:

$ arecord -r 8000 -f U8 | airpipe chat | aplay -r 8000 -f U8

(This example is Linux-only!)

In one terminal:

$ ffmpeg -f alsa -ac 2 -f x11grab -r 25 -i :0.0 -vcodec mpeg2video -ar 44100 -s wvga -y /tmp/video.mpg

In another:

$ airpipe screen < /tmp/video.mpg
