Umm,, I'll bite.  If www.sco.com and www.caldera.com are on the same IP,
how do you create a DDoS that wouldn't take out the Caldera site as well?

A sheer-traffic DDoS will hurt both.  A synflood will hurt both.

The webserver that's listening on port 80 doesn't know which site
is being connected to until it actually reads in the HTTP/1.1 headers and
looks at the Host: tag - and if there's enough things arriving with
'Host: www.sco.com', it will require some *very* creative filtering/limiting
to keep one website working while the other is down....
