Does anyone know how to upload files as chatter feed items from visualforce page using Jquery plugin PLUpload?

Hi everyone,

My requirement is to upload a file using HTML input type="text"  rather then <apex:inputFile> as i need to upload multiple files using PlUpload Plugin.
PlUpload uploads the multi-part file to my Controller action but i am getting Name of the file rather then its bytes.

Does anyone know how to get the uploaded file bytes using HTML input type="file" ..? My requirement is not to use merge fields where i take Document/Attachment object and use <apex:inputFile> .
