No - I have visited two universities in the past month in France and each of them has its own Wi-Fi logins and passwords. And then one more a few months ago in Poland.
AHHHH - I just called a friend of mine at one of the French schools. He told me that this is for researchers only and thsi is why I was given another (permanent) access.
I stand corrected and I apologize. This is actually awesome. Working in the field, this is probably one of the most interesting deployments I have seen over many years and I will have a close look at it now.
