Sorry, I will be editing this and re-eiditng over the next week. I plan on submitting this somewhere, but absolutely not before some major (near rewrite) changes.

I wrote this freehand late yesterday and it rambles and has little cohesion. I hadn't slept for 36 hours (never mind, that's another story for later).

In any case my concentration was terrible at the end and I gave up and posted what I knew would be messy.....and looking again it is.

The ideas are sound and well expressed however (I think) so I will definately mess around editing this a lot more.
