I recently came across Charm, they build tools to make the command line glamorous.

They’re using SSH keys for authentication, so no one has to create an account. They also have their own Charm cloud, but make it very easy to host your own Charm server. The Charm server can be used with Skate, which is a personal key-value store that is backed up to the cloud.

I also really enjoy their graphics for their products. Check out the Charm website to see what I mean.
