Well I went ahead and stuck my neck out.
I wrote up a good sized document with suggested rules for future GGP events and sent them to Bob Gillespie earlier this week. I think it's too long a document to paste into this thread, so here's a link to a page with the document.

I nearly pasted a couple excerpts into this post. But I'd rather you see the whole document.
