I thought of that, but I'm not sure a challenge meets their "Compliance
Standard." Using Habeas means making some statement about my email which
perhaps not everyone agrees with. I'd rather just avoid it than have a
possible dispute with possible legal ramifications.
I see Habeas as meaning "you want to get my mail" (or maybe "I promise this
isn't unwanted") while hashcash means only "I want you to get my mail."

That sounds nice, but, well, it isn't. If it were, I'd be worried about
how my MUA handled the case where there are many of them running at once.
Since I started queueing things, I've seen as many as four in the queue at
a time. I wouldn't want them all duking it out for the processor at once,
and I'm don't know if the MUA will queue or just fork. Come to think of
it, 'round these parts, MUAs don't do that--they expect to have an MTA that
does it for them.

That's helpful, thanks. I probably won't use it, though. I really DON'T
want lots of hashcash minting going at once. I really DO want them to go
single file through the CPU.
Incidentally, since I last wrote, I implemented interrupting in the
daemon side of my little system. It can use STOP and CONT signals to
interrupt low priority tasks with high. This way the stuff I've designated
to be more important (or fast) always goes as quickly as it can.

Thanks! I'll look at that.
