Well, Plimus is made for shareware and in my case, I have Plimus issue the registration key on my behalf to the customer in the email once the sales is cleared. In that email, you can customized to include a download link on your website or either upload the ebooks to Plimus so that they will deliver it to the customers via email. As for what shows on the customer's Credit Card Statement, Plimus allows you to set a default name to be used across all your products or you can customized it per product. It will basically be tagged as PLI*ProductName or PLI*MerchantName . In my case, I customized it per software so my customer knows what the payment was for.
