It would be nice if Business::Stripe worked with the Perl standard for credit card processors, Business::OnlinePayment. Right now Business::Stripe is kind-of like havin a database driver that doesn't work with DBI.

We are of course aware that tokenization and recurring payments are a new part of the base B:OP API and are definitely willing to work with you to extend and standardize that base API for your needs. See the AuthorizeNet, PayflowPro and CardFortress modules for examples of modules that provide similar features.

This is of course a wishlist "bug". :)
