Woof – simply exchange files

Woof—simply exchange files (via). Ultra simple file sharing for local networks: run “woof filename” to start a local web server which will serve up that file, just once, and then terminate. Can also serve up an entire directory as a compressed archive. Written in Python, as a single script which you can drop in to your ~/bin. “woof -s” serves the script itself, so you can easily pass it to someone who has a file you want.
