Goggles comes with source code (but not explicit license).

Seems CityLens doesn't have public source code. (Correct if I'm wrong).

Goggles.py is not (syntactically) working with python-2.5.2 (this is what we have on Maemo).

It is not working on Ubuntu either, maybe there are something changed on server/API. One comment point to the test made by Java, and that works under Ubuntu: http://prodroid.com.ua/?p=385

So that Java could be rewritten (back) to the Python and keep in mind python-2.5 and then we have it on N900.

That java-file is 193 lines and imports could be the same than old python goggles.py have.

It is only commandline tool for testing API.
