Flatpaks now are well integrated into the Workstation as a means of packaging applications, and offer advantages and for flexibility of installation, for security, and for upgrade robustness, but at the moment, the only sources of Flatpaks for users are 3rd party external repositories.
For the last year, we've been working towards having Flatpaks built from Fedora packages within the Fedora build system. Getting this working and available to users for Fedora 29 is within sight, but there are a lot of moving pieces, and getting relevant people in the same room would be a big help in making sure that everything falls into place.
I'd see three things going on at this hackfest:
General discussion to summarize status, get all the participants up to speed, and come to an agreed list of things to work on. (First 1+ hour). This would be kept high-level. Fix remaining issues, or at least know how we are fixing them (Fedora infrastructure members, contributors to the core Workstation pieces) Start creating Flatpak content - can be contributed to by any interested Fedora packager. The second and third activities would be parallel and independent, but I think would interact usefully - in providing help to the new contributors and providing testing and feedback to the people working on the infrastructure.
