No, not those kind of nodes. Graphical nodes. Yanobox has announced a new effect that creates animated connections of lines and graphics that seems perfect for visualizing boring lists in creative ways. The samples on the web site are really beautiful. Information designers are going to love this one.
It runs on the FxFactory architecture, which is 64-bit native and compatible with After Effects CS5 on Mac OS. Check out the video at http://www.yanobox.com/Nodes_Video/
