Even if the court decides that companies can be compelled to provide information stored in servers in other countries, I don't see this going anywhere without mutual reciprocative agreements with other countries. Very few countries would want data about/owned by their citizens to be given away directly or indirectly. Even then, it may be a long drawn process, just like with any other cross border criminal investigations.
