I am an American and I just want to point out that my latest startup (
http://www.efficito.com) is a Limited UK company, and my co-founder is from the Netherlands. It would certainly be to my advantage if things change. We offer cloud-based ERP, and you might be interested to know our main hosting server is currently in the Czech Republic. We are also paranoid about security (all access is encrtpted, and we are looking at encrypted storage for virtual machines, and much more).
I would love for things to change. I really would. What I worry though is about attention span of even decision makers on the business side, and what the alternatives are. The ideal situation would be a bunch of smaller private social networks able to interop (the Diaspora model) but it isn't clear there is a financial way to make this work.
So I hope it changes. I really do. I just am somewhat pessimistic :-P
