DisplayPort monitor with USB hub, switch to another machine with all USBs?

So, I'd really like to just be able to sit down at my desk, with my gaming pc all connected up and working, plug my MacBook Air in to the DisplayPort and pick up all the USB devices.

The graphics card I'm using on the gaming PC is a Radeon HD 7900, will this happily see the USB devices connected on the monitor?

Is there some kind of DisplayPort only switch that I can just press a button and it'll switch it all over to the other machine?

Can't really find much information about this kind of setup, anyone have any experience?

Dell UltraSharp U3415W has the same capability. Here's how it works, I would imagine other Dell monitors are similar.

There are four USB3.0 "A" ports you can use to plug USB devices into the USB hub built into the monitor. Three are on the same plate as the power/video connections (bottom backside of the monitor), and the fourth is out on the edge of the display at the back, like if you wanted to have an easier to reach place to plug a USB key.

There are two USB3.0 "B" ports to plug cables which would go to a computer. These are on the same plate as the power and video connections They're labeled "USB 1" and "USB 2"

In the menu for the monitor, you bind the USB ports to a video input. For example: "USB1 goes with DisplayPort" and "USB2 goes with HDMI"

Then you run the USB1 and DisplayPort cables to one computer, and the USB2 and HDMI cables to the other computer.

When you use the buttons on the monitor to select DisplayPort, your USB devices are automatically connected to the matching computer. When you change display input to HDMI, the USB hub automatically gets switched to the other computer at the same time.

It's quite slick -- But obviously you need to think about for example, USB storage, which doesn't want to be ejected uncleanly, which it will be if you switch display outputs without manually ejecting the USB key first.
