Disabled local file storage

Hello,

Is it possible to simply "disable" the uploadDir path? I am using this with jquery-cloud-file-upload-middleware and don't want the files to be stored locally, i just want them on S3.

I know this question is most likely misplaced, but with no option to contact the person who forked this library and implemented the S3 functionality, then i'm hoping the library it's based off might support my required solution with a neat trick.

Thanks,
