It can run 24/7 on a ramdisk. Plus it could be convenient if you have nothing else and you want to get in touch with someone over I2P, much like Tails does with Tor for a similar purpose.

A good bonus might be to include a couple of shell scripts to automate deploying a few things as well, and even keep those maintained as stand-alone, I surely wouldn't mind using those on virtual servers and contributing to such thing to automate deploying something like an FTP server or an email server for easy and convenient data exchange and communication.
