My dynamic IPv6 prefix hasn’t changed in a couple of years. It only changed because I reset the router config and that changed my DUID. That’s good enough for everything I host. I don’t even bother with dynamic DNS anymore.
I wouldn’t bother with trying to host an email server from a residential connection though. Even if you can get your ISP to open port 25 for you, many email servers won’t accept mail from residential IP addresses.
If find the missed call notifications to be very helpful. I never remember to check my phone, but I’m on the computer all the time. I also like the ability to remote control the music player from my phone since the computer is hooked up to an amplifier with speakers in multiple rooms.
