Thank you kindly, Melanie, for a patch which:

Previously, upload charging was possible only for UPD uploads. 
This is because UDP uploads are charged by the viewer, while in CAPS, 
this was changed to be server side, so hackers couldn't avoid 
paying the upload charge. This patch adds a method to allow 
implementation of this serverside charge.
