With yousendit they have to at least register for an account then they can upload/download from the web interface from folders you make for them and set permissions on. They can download the app too.

If you didn't have the need for them to upload you could just use your website online space without extra cost.

Upload FTP to your domain web space is still a free option too if they give you enough ftp accounts but that does require a bit of internet knowledge for the uploader to install/launch an ftp app.
