Share code/.bash_history between terminals (and store it securely in the cloud)

We are building a tool for developers who work in many terminals and want to easily sync data/code snippets/bash history between them. Think https://github.com/holman/boom in the cloud. We would love to hear about your pain points working in many terminal windows to make our tool better.<p>If you need such a tool, please sign up at http://getboosh.launchrock.com/
