HTML5 based (Multi) Upload Component planned

Hi,

are there any plans to implement an HTML5 based Multi-Upload Component in Vaadin Core?

I know I can use the MultiFileUpload Addon, but that has an issue with cancelling downloads. I found another Addon “html5-upload-vaadin” which builds on Plupload or Fineuploader, but that doesn’t support multiple file uploads, which makes it a bit useless for me.
