While not really unattended, I have had a BBB running Debian 7 ( wheezy ) for as long as as 45 days with no reboots. I have accessed it via SSH, and did some testing on it during this time.
A couple of differences here besides the obvious is that I have it powered via USB ( from a Windows 7 laptop ), and the Debian used is a network boot configuration. e.g. it uses no emmc or flash media in this configuration. Anyhow, the BBB in this situation *would* need some form of UPS, as when coming back up form a reboot( power blip would do the same thing ) sometimes it can hang. Either that or a remote "switch" for resetting the power on the device. Also as Robert mentioned above read only media would be a requirement if you expect to get any reasonable life time out of the device. However, the BBB *can* also boot via a USB device if that is also an option. I'm thinking hard drive here for longevity but . . .
