I think the metadata issue is really interesting, and I'm interested
in what various schemes (P2P, Dark mail alliance, etc) are doing about
it. But I think you and I are talking about different problems: your
main concern (which is a valid one!) is that encrypted emails still
expose metadata, whereas my concern is the fact that hardly anybody is
currently able to use email encryption at all! I think both concerns
are fair, and both are worth trying to solve.
