re: What would an advanced intelligence want from us anyway?
"Want" is probably not an appropriate term; but I can imagine an advanced civilization forming a substrate for a super-intelligence, a "personal" entity who might be moved by pure compassion to take an interest in suffering at lower levels of being.
Have you ever heard of Ronald Pearson? He has an interetsing idea about consciousness: http://www.cfpf.org.uk/articles/rdp/s_rdp/summary-rdp.html
