Hello Hannes,

I do think that we should revive this thread, and I am sorry I have not
done more with it myself.

I also think that it is best to keep EtoysProject outside of trunk until
after the 5.2 release. I would not want to add anything to trunk right
now unless it is complete, well tested, and stable :-)
