VLC for iOS has a great HTML5 web interface to upload files. However, it was not of any use while trying to upload files from a remote console.
Here is the command you can use to upload a file from any shell :
curl -F files=@/tmp/movie.avi http://192.168.1.64:8888/upload.json
All you need is to replace the file name and the IP address and don’t forget to start the server on your iPad.
