I just added Rapportive to my google apps account. Looks promising, especially with Bantam Live integration (which I've been testing recently also). Feedback: the sidebar is sticky (moves with the scrollbar), which can be cool, but also interferes if I have anything else in that sidebar. Question: what makes Rapportive different/better than Etacts? I really like the Send+Remind feature that Etacts has, for instance.
