Hm, it looks like pufferpanel/pterodactyl are both generic game hosting services; my biggest annoyance is keeping the plugins up-to-date. And they are not made for that?
I found Fork, which is promising a minecraft-only application that will also do plugin management, but it's windows only (and I am using linux)
Hmm, the search continues.
Oh, yeah, MineOS seems dead :-) :-/
He didn't set a time in Q3?
