What's your hosting solution for external access? I'm asking because right now, Plex has a lot going for it in terms of allowing me to securely host my own server and share it with the people I want who are outside my network without actually having to open up ports or compromise my network security in any way. I couldn't imagine hosting costs on a cloud VM for a decently sized, fairly actively used media server, assuming you wanted to go that route. I guess you could set up a reverse proxy on a cloud VM and forward traffic into your local network, but then there's still the added network traffic costs for your VM.
