I was looking over the specs for Lion, and noticed that they were including Lion "Server" in the mix for fifty bucks. So, what is the server part of it? In my now two years experience with OSX, I know that it runs on a modified, but full version of BSD Unix. I can make a server out of any OSX machine and have done so many times from the command line. And all kinds of servers - file, video, web, backup, etc, and accessable from both other OS's.
So what do you get with what Apple is calling Lion Server? Administration GUI, I assume? Or maybe just the right to attach to it, in other words, a license pack?
