Why no love for multiple/nested remote connections? I really don’t get this one. If you’re using Apple Remote Desktop (or Screen Sharing in Leopard), you can’t remote into a machine that’s running a remote desktop client.
That’s unfortunate, and something Microsoft’ Terminal Services does with no fuss. In fact, it’s specifically designed for it. Connect to a gateway machine (in a DMZ, say), then on to whatever box(es) you need. On the whole, TS is really great, actually; something that’s really pretty damn complicated to get right, that they do excellently. The biggest pisser? ARD costs $400. Maybe they expect administrators to do everything at the command line? Sure, you can, but a slick GUI makes mundane tasks faster and easier. The lack of these tools is, IMO, a huge impediment to OS X making a dent in business/enterprise environments. It’s too bad; I’d love to see something like Microsoft’s System Center Essentials (full disclosure: I worked on it) for Macs.
