Between releasing source code early, and polishing and optimizing it for
some time in the future, let mine be a humble vote for releasing code
early. You may be glad you did. There are probably others like me, who
think the idea is sound enough, and want to try it out and gauge its
deployability. There are probably some here who would be willing to put
an FTE server transport plugin on a public relay.
