Unity + EC2 + Render

I need help/advice on how (and if it's possible) to have a Unity application run on an Amazon GPU enabled EC2 instance.

The app basically renders millions of different images from the loaded scene, renders the results, calls getPixels and writes the results to disk (or Amazon S3 ideally). Sort of like a render farm.

I haven't been able to figure out how to make this work at all on Amazon - though I have it running on my local machine (which I'd prefer to not use for this purpose).

Any advice, direction or links that could help determine if this possible or a waste of time at this point.

Thanks
