Andreas Brekken, coming back to you:

A proposal to make the financial part of such a use of a database fair:
1) Everybody who wants to use it, has to pay a yearly amount.
2) This amount is higher for users with commercial interest (i.e. every book/article author or such). I.e. hobby users pay 30-50Euros, commercial users pay 200 or so.

Or, alternatively, if possible: Every extrated loss costs a defined amount. But this again needs a certain extra effort...

Here in Germany, we would start a "Verein" for such things.
