App purchase/donation work

[Alexander Larsson]

I'm about to start looking into more detail at the application
purchase/donation work, as discussed previous and documented at
https://docs.google.com/document/d/1zE_QbB6mtdhjH5bsFdf9kPrYvjKAMBRl4uSRYDt-BqQ

Other than the document above, is there any coding work started on this?

My initial focus will be on the dbus API and how to best integrate
this into flatpak/libflatpak/gnome-software (rather than the details
of the authentication and other server side stuff). But, if there is
any existing work on the other stuff that would be great to be able to
look at.
