Feature to allow user to reply to private 1-1 message via email in HipChat Server

Scenario & Suggestion

When users that are logged in to HipChat client have status set to "Away", when they receive a private 1-1 message they are sent an email notification with the contents of that message, and a subject line like this:

"john_doe sent you a 1-1 message"

As most Cloud services today (LinkedIn, Facebook, etc) allow users to reply to email notifications like this with a message, we feel HipChat Server should have this functionality as well - we should be able to reply to private 1-1 messages by email.
