Hi,

This is really at the spec stage. I'm still reading my way through the logs here so just filling out information as I go, but any early feedback much appreciated. Once we've got a spec settled, I'll start CADing up the design. There are a lot of "spec?" questions below, as I can't really find super-clear answers (perhaps I'm looking in the wrong place). Also: I think I've covered all the categories... but have I?!
