With async payments, the pain of hashcash is very low. And, this only affects people with hashcash installed on their systems. So, I think it's reasonable to keep it. What would be nice (I don't have the clue level and my papers aren't in order...) would be to be able to rerun the async payment processsing (that starts when a reply is created) whenever there are addresses in the header (perhaps starting a few seconds after the cursor is not in a header line). -- Greg Troxel
