I have built RPMs for Fedora 19, and have used them for a while. Before starting to "lint" the SPEC with packaging guidelines, is anyone already working on this? I am also starting the namecoin RPM tonight. Namecoin is perhaps more interesting than bitcoin, as it is a distributed DNS registry that does not require a root server. Both require elliptic curve modules in openssl - which is the main reason why they can't go in Fedora at the moment.
