The GPL family of licenses were written under legal counselling of actual lawyers. They are, however, first and foremost an US product, written to be enforced under US laws. It is no surprise that other countries have different legal systems under which the terms of a software license can be difficult to apply.

For a license similar to AGPL but written with the whole European Union legal frameworks in mind, I'd suggest having a look at The European Union Public Licence (EUPL):

I am european, so I was considering using the EUPL for a new open source project that I'm planning. I'd love to get some comments from HN readers, regarding that choice.
