I'm currently putting together a worked example of the problem we looked at last Friday. I'm hoping to get it done this w/e.

I recall a few people saying they would do something similar. I suggest that if you've got a few of these, you put them up on your website (or mine, if you prefer) and we can have a round of email discussion around them.

From there, we might organise a later meeting around the main issues that arise.
