Doesn't sound so dissimilar to the EU's Internet tax that was planned years ago (not sure if its email tax plan was part of the same thing). I don't think it would be unreasonable to assume that this plan would get some support at European level.
In the UK our last government imposed an Internet tax, but at a flat monthly rate. Fortunately, it was scrapped.
There have been some schemes in Europe to tax Internet-related services, but they were mostly a result of lobbying and at least benefited some group, like unionized film makers or ISPs. But the difference is nobody welcomes this tax.
