Actually, there was another idea I had a while back. I was thinking of coming up with a very simple post format, more template-oriented the way that PostHASTE situates theirs, and would just write a converter utility that enables me to convert a library of existing posts into the simple format. This would be my fallback if there were any sort of legality issue utilizing an existing post format. Personally, I believe there should be an open post format, so that they can be interchangeable across all CAM packages that support the format.
Anyway, thanks again
