Some receivers (like this Sony one) look to be marketed to support HDMI passthrough
Therefore, it looks like there is such a thing although I'm not sure it satisfies your constraints

With limited HDMI inputs on my TV and so many HDMI components available out there including the NETGEAR EVA 8000 HD and Apple TV, I am going to have to either go with an HDMI switch (expensive!) or manually swap out components when I want to use them.
I know on older A/V components, you could pass audio and video signals through the device so that if the device was in use, it would take over control of the line.
This may sound naive but would this be possible on newer components with HDMI? Is there an example of this out there for the port-challenged folks like me?
Can a man have too many gadgets?

There are plenty of receivers and hdmi switchers available on the market. The receivers tend to be on the higher priced side, but the prices have been coming down. I'm a big fan of denon receivers, and they have HDMI a/v receivers in their lineup.
The issue with HDMI that component video or S-video switchers didn't have is the HDCP protection built into the HDMI spec. This is a result of piracy protection to keep bootleggers away from High Def content. unfortunately, this is causing issues with "duplicating" over HDMI, which is what a receiver or switch does.
So keep a lookout for this when buying HDMI products.
