Plug servers. Google it. Marvell ARM chips mostly. I have been thinking about trying to build a little turnkey linux OS to run on those things that can provide similar functionality to what you are talking about.

Alas the technology does not seem to be quite there yet and the work required to get basically a full personally hosted webapp suite is not trivial. That said, I think in the future we will see a lot more 'appliances' that run as VMs or on low cost low power all ways on hardware. Backed by a business model something like wordpress. Meaning that there is a dot com where you can get it remotely hosted for you, and there is a dot org where you can download and host the app yourself.

Plus stuff like the personal router project http://pr.lcs.mit.edu/ would make a pretty interesting paradigm change.
