You mean things like the FreedomBox? A series of gadgets everyone can easily buy and set up in their bedroom somewhere to work as a personal cloud? I think even that is a hard sell. The user has to care enough to buy it, and go through the set up process.

It may ever amount to anything but I'm more hopeful for things like Beaker Browser or SafeNetwork (or at least ideas like SafeNetwork, if not SafeNetwork itself). The idea is to have computing resources right from the user's own laptop or desktop provide the backbone of the decentralized network. So instead of "buy this thing, plug it in to your house, spend half an hour setting it up...." it's just "Oh, my friend is on a social network that works through Beaker Browser. I installed Beaker to connect with him." And the person's device is then contributing a share of resources to host dat sites (the protocol Beaker supports alongside HTTP) automatically.
