The national cloud

Google has launched Google Apps for Government. It is a variant of its cloud application suite (mail, calendar, docs, ...) that is guaranteed to store its data in the US. Similar services for other countries may follow. It is clear that one country does not want to store its data in another country for security reasons.
It is interesting to see if this service will also come to Google App Engine and commercial applications.
It may remove an important legal hurdle: the country where an application's are stored will determine the laws that will be applied to them and under which jurisdiction actions on your data can be ordered.
Note that although Google guarantees where your data are stored, it does not guarantee where your application runs.
