Hey James,

Yes its somewhat complicate all round - the best place to start is with the RasAsyncUpload documentation on the telerik web site - its talks thru most of the usage cases.

DNN also add some complexities in terms of how the handlers function - we wound up rolling our own handler to manage the upload to temporary storage which then eventually became a direct upload to azure - then when the Save command is fired on the page we handled the rest of the processing.
