Then you just need smart client that splits data 3-way into 3 different national jurisdictions. The data for each file is split in 2 and send to two different nations and the encrypted keys for decrypting each file are stored on 3rd with optional self destruct/dead man's switch. Everything is done client side. The hardware costs seem reasonable. And if someone is to subpoena the data needs to fight the legal system in 3 countries and obtain the master key.

There are only two solutions:

1) Encrypt your data before sending to the cloud, so that server access becomes irrelevant. (This is what Tarsnap does.)

2) Change the law to stop or change the programs.

Neither can be accomplished by Amazon or any other single provider.
