Also meant to say that Google (and others) support a 'Noarchive' instruction (not quite sure if this can be implemented in robots.txt or only via robots meta tags and x-robots-tags - if anyone can tell me I'd be grateful) which I think would fulfil this type of instruction - index, but don't keep a copy.
