Since there is every day a release, I'd suggest to make a 9999 or similar that points to afl-latest.tgz.
Do you think that's neccessary? Most likely the "more than one release a day" phase was part of the early development of a project, I don't expect that to continue. It's already considerably slowed down. If you feel you want a live ebuild go ahead, but I think we don't really need it.
No need for a live ebuild I think.
