>I think that one's home computers can probably handle the load of searching all of one's own data.
You seem to be implying that I have one computer at home. I mostly use the computer in my pocket, but sometimes I use "my" computer in "My office" at home. Sometimes I use "my wife's computer". Many people I know have a computer attached to their tv. I'm looking into putting a computer in my garage. Someday I'm likely to get a laptop or tablet computer for travel (I've had these in the past).
We need to get off the mindset of one computer per person - it was never really true, but for the average person today it is less true.
Ideally we might have one server per person. There's no reason, really, why I shouldn't be able to run my webmail, media store, calendar, lightly-trafficked blog, etc. from an RPi sitting at home and just use them wherever I like.
I used to do this with Owncloud, and Sandstorm has done some cool work in this field, though ISP's of course make it challenging. Also, it does raise the risk of everyone contributing to massive botnets.
