Exactly. Depends on how much risk you're eager to take. And as a non-lawyer I'd prefer to take none. Most guides for laymen I've found stated that if it's not just about your kittens or vacation, it's not "purely private" any more.

For instance, aforementioned Lennart who writes about his open source projects preferred to provide this info.

I've also heard that the lawyers in this extortion business know some tricks to make the case land on a judge with "correct" interpretations of the related paragraphs. But that's not for sure, I've never been sued in Germany luckily.

Oh, you're the guy behind zturn-stuff =) Thanks a lot, that's given me a great starting point to hack with this board. I hope I'll convince meta-xilinx maintainers to add support for it soon.
