Thanks for the good luck wishes, but I don't intend to throw money towards enforcing the license at all. I mostly don't want to be liable for code that I open source.
And restricting it to EU would solve the problem that e.g. WTFPL or UNLICENSE have with countries that don't acknowledge public domain.
This is more a question out of curiosity for me, and many people react allergic to viral licenses, GNU or RMS so I was looking for alternatives because I also heard there were issues with CC-share-alike.
