it could be impossible. from the documenation:

raw
     The raw option allows faster access to a file, because no Erlang 
process is needed to handle the file. However, a file opened in this way 
has the following limitations:

         * The functions in the io module cannot be used, because they 
can only talk to an Erlang process. Instead, use the read/2 and write/2 
functions.
==>     * Only the Erlang process which opened the file can use it.
         * A remote Erlang file server cannot be used; the computer on 
which the Erlang node is running must have access to the file system 
(directly or through NFS).
