I may be missing a point, but I create a regular, non-encrypted snapshot using 
Colin’s AMI maker, which then gets copied across regions into an encrypted one. 
From that one, I can successfully boot a larger, encrypted EBS instance.

The main reasons for using encrypted EBS are two: compliance with “best effort” 
in case the discarded data storage fell into someone’s hands, and an onion-like 
approach to security, getting an extra (though thin) layer at pretty much no 
cost. I cannot see a reason why not to use that feature provided it works in 
the background without any visible performance issues.

Many thanks,
Rafal
