Robot Framework - Test Automation Tool

Looking at Open Source solutions for Test Automation the Robot Framework is probably one of the best ones out there:

http://code.google.com/p/robotframework/

On the pro side there is definitely:
- Very good and extensive documentation
- Very active forum
- Writing Tests using Keywords
- Lots of ready-made Keyword Libraries available
- Good integration to CI servers

On the con side I see the installation that can require quite a lot of different tools (python, jython, RF, RIDE)

There is also a G+ community that is just starting off:

And if you want to get a better overview on the Robot Framework this tutorial is hopefully useful (btw. I know the author of that one ;)):
