No holy war, but I find it inconvenient the way PEP uses the "upload/download" terminology .

I fully agree what is said in Wiki on the terminology:

Technically if the user uses the receiving device to initiate the transfer then it would be a download and if they used the sending device to initiate it would be an upload.

Since the PEP is the side that initiates the transfer it would be more logical (and naturally enough) to call the process as uploading...
