I would love to build telegram desktop (tdesktop) using git-rpmbuild but I'm not sure if that will be successful. Anyway, I would love to see this project growing, I see quite some potential use cases for my regular projects as well as the occasional quick fix to a project I otherwise don't touch.

Do you have anything in mind for supporting rpmfusion? (That would be the first hurdle for tdesktop. Probably not too hard to implement.)
