The short of it is, yes, that's under active development. It'll probably launch in March. Aaron Coleman and Erica Larsen are building a Flash interface to it; Joel Brehm in Research, under contract to UComm, did a fantastic job of creating not only a map, but a full 3D model of both campuses.
The short answer is, real soon now.
