FlorianMueller writes: After pursuing Microsoft and Intel, European Commission Vice-President Neelie Kroes is now preparing an initiative that could have an even greater impact on the IT industry: a European interoperability law that will affect not only companies found dominant in a market but all "significant" players. In a recent interview, Mrs. Kroes mentioned Apple. Nokia, RIM and Adobe would be other examples. All significant market players would have to provide access to interfaces and data formats, with pricing constraints considered "likely" by the commissioner. Her objective: "Any kind of IT product should be able to communicate with any type of service in the future." The process may take a few years, but key decisions on the substance of the bill may already be taken later this year.
