Yeah. In fact, there is some hack to be able to have a progress bar when
using multipart/form-data (see php/pecl upload module), which is making xhr
request in parallele to the file upload just to check information related to
the upload progression server side.
The idea i have in mind personaly :
* have a config option to force fall back to use a <form> tag in uploadmnrg
plugin
* test node-formidable (i bookmarked this node module just yesterday ;) )
* provide server side node source code to handle octet-stream method
* provide server side node source code to handle multipart/form-data method
* provide poc to handle a progress bar using multipart/form-data (but using
node server side)
