I believe you'd be able to do this via something like
base64_encode()ing the contents of the file, then sending the other
details along with the POST request just by setting that into the body
of the request, as a query-string formatting string.

You're likely to have some "fun" dealing with big files using this
method though, don't know if that's going to be an issue for you.

Something like this should be a starting point (not tested at all :) ).

<?php
$file = file_get_contents('filename.ext');
$file = base64_encode($file);
$body = http_build_query( array( 'file' => $file, 'name' => $name,
'whateverelse' => 'something' ) );
$result = wp_remote_post( $url, array( 'body'=>$body );
echo wp_remote_retrieve_body($result);
?>

This is all assuming you're sending a file from WP to a remote site,
and obviously the format will depend on what they're expecting.
