If you add 'unique_names: true' to the S3 example, files are uploaded to Amazon S3 with the original filename instead of the unique filename.

This worked for me

BeforeUpload : function(up,file){
var file_name = file.name;
var extension = file_name.split(".").pop();
up.settings.multipart_params.key = up.id+"."+extension;
up.settings.multipart_params.Filename = up.id+"."+extension;

Basically override the key and filename with the id of the upload and adding the file extension ,.

Same problem here.

@gafitescu thanks for the solution

(I had to be careful about overwriting the key there, though, because in a subdirectory)

@gafitescu's code didn't quite work for me. I ended up with:

BeforeUpload: function(up, file) {
    var file_name = file.name;
    var extension = file.name.split('.').pop();
    up.settings.multipart_params.key = this.task.get('id') +'/'+ file.id +'.'+ extension;
    up.settings.multipart_params.Filename = this.task.get('id') +'/'+ file.id +'.'+ extension;

As in the case with rename option new file name is sent as separate param and handled by our upload.php. Obviously in the case of S3 there is nothing on Amazon Side to handle custom params, so one basically has to set it manually in the config.
