Android Device not appearing as process for MonoDevelop

I am using:

• A Samsung Galaxy S II

• A Macbook Pro (Lion)

• Unity 3.5.3f3 with Android License (Not PRO)

The Macbook Pro is sharing its ethernet connection through wi-fi to the Galaxy S II device. The Unity App is built with 'Development Build' and 'Script Debugging'. When I open the "Attach to Process" in Monodevelop I only see the usual 'null' and 'Unity Editor (Unity)" processes.

The device responds to adb logcat when connected with USB if that helps.

Thanks a lot.
