What's not very clear to me is if my Glacier files are a subset of my Dropbox files, or a separate datastore.

I only have 2GB of Dropbox space because I never upgraded. But I have about 100GB of archive data I'd probably throw into Amazon Glacier if it were convenient.

Do I need to open a 100GB Dropbox account before using IceBox?

What's not very clear to me is whether they have any idea what they're doing when it comes to security, or how to respond properly to a legitimate security hole. It's difficult to trust someone who builds a service like this and leaves securing personal keys as "something we'll get around to."
