# Add this to /etc/profile and source it, then you can type `drop [file|folder]` to transfer
# files to some remote host, or 'drops' to list all drops, or 'undrop [file]

export DROPHOST=example.com
export DROPUSER=username
export DROPPATH=/home/path/to/folder
export DROPWEBROOT=/drop

# drop a file or folder & copy the resulting url to your clipboard
function drop() {
  echo "copying $1 to remote"; 
  scp -r -P 86 $1 ${DROPUSER}@${DROPHOST}:${DROPPATH};
  echo "http://${DROPHOST}/${DROPWEBROOT}/$1" | pbcopy;
  pbpaste;
  }

# list current drops
function drops() {
  ssh -p 86 -l ${DROPUSER} ${DROPHOST} "ls -1 ${DROPPATH}";
  }

# undrop (delete a drop)
function undrop() {
  ssh -p 86 -l ${DROPUSER} ${DROPHOST} "rm -iR ${DROPPATH}/$1";
  }

# tar & gz a before it's dropped
function dropgz() {
  tar -cvzf "/tmp/$1.tar.gz" "$1";
  cd /tmp;
  drop "$1.tar.gz";
  cd -;
  }

• tarbal/gz is easy enough as we can carry that out in the /tmp folder
• invite only drops we can do by generating a random string and scp'ing to that folder
• private drops we can drop in to a /private folder that's not in web space or has http auth on it
• scp has built in bandwidth limiting, specified in Kbit/s, so that will do for "Dropbox won't hog your connection"
