This is great and very user-friendly. As a quick & dirty alternative for people using the command line, you can easily send files by using netcat.
To quickly copy file from one machine to another.
# on target machine
$ nc -l PORT > file
# on source machine
$ cat file | nc HOST PORT
To quickly copy an entire folder:
# on target machine
$ nc -l PORT | tar xf -
# on source machine
$ tar cf - FOLDER | nc HOST PORT
And on top of it you can add pv in pipe for progress bar
