It's a killer-app, in the sense that a warm coat is, during unanticipated
cold weather.  Do any of the current WinTel-wallmart boxes do this ?

I was hoping that someone would point me to Linux facilities, since
I had a vague feeling that it already existed.  Although since it would
have to work rignt down at the kernel level, it's not just a trivial add-on.

I'm asking a socio-economic question & Ya'all giving only
technical p.o.v.

What is a typical duty-cycle of a home-server ?
What if each year there's an extra 20 million Chinese
home-servers running 7/24 ?

Subject: blogs kill groups; cars kill trains;  unsustainable ?

Except for the most technical, newsgroups have all migrated to blogs.
So my ISP newsServer is often disabled/sluggish.

When I try blogs, I see that 'the whole book' is transfered back&forth
each time an addition is made. And of course there's no concept of
threading, which gave further specialisation and opportunities for
bandwidth economising.

So then I read about RSS, which 'activates on new/additional stuff'.
But does this allow Txing of only the new material, or is the whole
book still Txed ?

What do they use in China/India ?
I can't believe they'd use such 'convenient'/wastefull methods as
we obsese slobs do?

== TIA.
