Why wouldn't you use HTTP? It does not have any overhead when uploading big 
files.
There are many cases when HTTP is quite convenient, and uploading 50, 100MB or 
even 10GB 

is fine from technological point of view (for example YouSendIt)

Currently there is no technical limits on file size upload, but:

- It is limited to 64MB by default, this can be changed by setting: 

  security.multipart_form_data_limit to the required size in KB.

- For large files it is better to use save_to() member function of http::file
  which would cause rather file rename then copy.
