Perhaps of interest, old thread about a proposed integrated donation system for community apps from maemo-dev mailing list: http://lists.maemo.org/pipermail/mae...ry/023980.html
The system now is uncoordinated and inefficient because there is no link between downloading an application via the repositories and getting an indication of the compensation scheme.
There needs to be a revision of guidelines for applications to: 1. provide a project page on t.m.o. for the application, with the first post (or two) kept updated with downloading and operating instructions 2. with the download information a donate link or indication of compensation method
