FYI, Cisco have published documentation and software to convert the DX70/80 Android device into a pure Telepresence video conferencing system, like the LARGER telepresence units.
Docs:

You'll lose the Android / Jabber / apps functionality, but you gain full telepresence (eg Tandberg) functionality.
