I'm just learning about joinmarket, so please forgive if this is a dumb suggestion, already implemented, or whatever.

I was just wondering if the weaknesses quoted below could not be overcome by something like:

1) takers provide multiple receive addresses.  say a random number between 5 and 20.
2) total output payment is divided up randomly and sent to these addresses.
3) each payment is time delayed by a random amount between 60 seconds and max secs, where the taker can define max secs.
