Thanks. ESXi and VSphere sound like they are what I'm looking for. The reason I've been using something(s) like Teamviewer is because of the zero-config setup.
When you say "You type in the IP Address of your ESXi Server", that's assuming that the client has a static IP, correct? And with stuff like Remote Web Access and RDP, you have to get into the router to allow port forwarding, etc. That's what I'm trying to avoid. Essentially, if the client says, "Not quite what we're looking for...", I'd like to be able to walk in, take a box back, and be done with it.
