The quickest way to launch a web server for sharing files. All you need is Python…or Ruby!

Original in Python:

My Ruby version:

  alias webshare='ruby -e "require\"webrick\";w=WEBrick::HTTPServer.new(:Port=>8000,:DocumentRoot=>Dir::pwd);Signal.trap(2){w.shutdown};w.start"'

And just go to the directory you want to share, use the 'webshare' command, and tell your friend(s) to go to http://<your-IP>:8000/
