The "It's Not Cloudy In The Cayman Islands" Work-Around for the CLOUD Act
1) Encrypt the data. Store it anywhere you like.
2) Encrypt the keys, and store the encrypted keys anywhere you like.
3) Hand the 'Key Encryption Keys' over to an external person-in-trust.
The Person-in-trust has to be outside direct control of the Corporation. Kinda like a Team of Lawyers in the Cayman Islands, operating under a strict predefined contract that cannot be overruled. The KEKs might be hashed and RAID-like smeared over a wide group.
