Nothing offical has appeared anywhere to date (as far as I've seen), however, searching the Tele Atlas site does turn up some information about the program titled Tele Atlas DeveloperLink. I also did receive this information about the program from a person within Tele Atlas apparently tasked with promoting it:

Tele Atlas’s DeveloperLink program is a free online resource that gives developers
access to the technology, business tools, and services to increase their potential for success in geographic application development. The program will offer extensive technical components such as free sample data and prototyping tools in addition to valuable business support that enables users to establish a business relationship with Tele Atlas’s global partner community. Furthermore, in the weeks and months to come, Tele Atlas will add forums to help users communicate and develop and maintain these contacts. See the program at https://developerlink.teleatlas.com.

The Tele Atlas website also offers up the following:

Once I created a profile and logged in I had access to a user forum (coming soon), and loads of documents about the Tele Atlas MultiNet solution, Tele Atlas GDF Viewer, and the GeoEngine mapping toolkit as well as links to third party developer tools and programs (like Autodesk, ESRI , GeoMicro, Telcontar, Mapquest, and others)
