Deepfreeze.io is cold storage everyone can use

I assumed this was going to be some sort of service for storing bitcoin private keys in... cold storage (i.e. offline, in an uber-secure physical bank/safe or something). Whoops!

I've thought about using Glacier but didn't seem worth the hassle. This I might use. Invite requested!

Why not just use Amazon Glacier directly?

I signed up for an invite a month ago or so when this was posted and still haven't received it.
