Kevin gave a talk on this in W. Bridge Obcos seminar, I think before the paper was published. Any way it is a solved problem.
If Sergi is unavailable or unfamiliar with this please let me know. I might be able to get someone to implement this.

Yes, exactly--thanks for the link, Chao-Lin. I think I forwarded this
same paper to Chris 5 years ago...
I'd like to hear from Sergi how Planck's approach in practice compares
to this, and what he thinks about implementation.
