[NTG-context] Choosing ConTeXt install method on Mac

Hello all I'm going to do a clean re-install of my machine (Tiger on PPC) soon, and I'd like guidance on methods of installing ConTeXt. I assume that (a) TeX Live 2008 with its tlmgr utility, or (b) ConTeXt minimals, are the two realistic possibilities - is this correct? What I'd like: - A clear way of keeping ConTeXt mkiv usable and up to date with Hans's latest version - An installation method that will continue to be maintained, and that is expected to be used by the majority of ordinary users of ConTeXt in the future ...So should I go for TeX Live, or the minimals, or something else I don't know about yet? Grateful for any advice... David
