OK in previous discussions I was under the impression that X- is the standard way to do it. Sounds like it is? but if it becomes a standard/ratified header you can remove the X-. In the interests of making that work if that happens at some point I will make the next version accept but not generate Hashcash, and generate X-Hashcash. That way if at some point it changes, we'll have less backwards compatibility issues without having to include the header 2x once as X-Hashcash and once as Hashcash.
