Didn't the US just sieze a bunch of foreign owned data from MegaUpload? Carpathia Hosting leased over a 1000 servers in the US and Canada to MegaUpload. There's no reason why they couldn't have seized a Rackspace server or an Amazon EC2/S3 server had they used that instead. If the government wants your data, if it's within their borders, they will get it.
