We are in contact with both Cardinal Commerce and PayPal to look into implementing this. I do not have a concrete date for when an update addresses this issue will become available, but it is something we are investigating. This is not a noncomittal answer, we are in the first stages which entails doing the research. Once the research has been completed we can move on and start implementing a solution.
Realistically, a solution will not be available by the 21st, but as soon as we do have one, we will make an announcement.
