Integration with Kavita Reader?

[viztastic]

Hi, thanks for the project!

Before I get into the question, I just wanted to share that the heroku link doesn't seem to work.

I'm wondering whether it's worth exploring an integration with something like KavitaReader for a user to make a purchase and then be able to read their purchased eBooks using something like KavitaReader. Kavita seems pretty full featured and might "just" need an integration to handle permissions for what a user can/can't read based on the eCommerce system.

What do you think?
