Hi Dan,

As you said, this was discussed a bit ago, and the conclusion at that
time sounded like it wasn't going to be a straight-forward fix. Your
experience seems to confirm that. I'm not sure there's been much
activity on this, otherwise. If you manage to get it to work, I'd
really like to pull in your solution.
