Is it possible to let users pay directly to other users?
Can Drupal Commerce be configured so that users can install their own methods of accepting payment? For example, "Jim" could setup his PayPal account as a method for him to accept payment for his services via the website. "Jane" could then send payment to Jim via the site. The website itself would not be an intermediary in the payment process. All users could have the option of setting up payment options for themselves.
