I should have self-replied - and the correct answer is that while that app is for the ipad / iphone - it DOES work - and it rocks. Simple solution - double click the home button on the ipad and slide over to airplay, choose ATV and go.
Works great!
What I could never get to work - and would still like to get an answer for - is where does CouchSurfer deposit download on the ATV - like what directly does it dump them into? I would like to ssh in and runs some tests.
