exactly. they have the form "chunk-xyz" (encrypted files). > Forgive me if this is already written in the project, but are there > plans to make a server-side way to peek at the file contents?

The server side idea has of course come to my mind before and once Syncany is somewhat stable, I'll start thinking about that a little more. But it is important to understand that if you use Amazon AMIs to deploy a (not yet existing) Syncany-server, you're giving away your secret to Amazon and you didn't win anything. If you choose to use EC2+S3, Amazon has (1) your files and (2) the key to your files, which is obviously a problem...
