There was a long thread on the EOS listserve (eos@xxxxx) last summer
on this topic. As I recall, the consensus was to not use canned air,
brushes, etc., but to employ a wiping strategy. They suggested that
one should google "ccd clean," to find methods that work and places
to purchase the necessary tools.
I think you're correct about Canon's strategy. The Canon cleaning
procedure is simply to raise the mirror to expose the ccd cover.
After that, you're left to your own devices. Some suggested that
canned air simply blew the particles around so they found another
place to rest or were replaced by others that you had stirred up in
the process. I know that I have a few dust artifacts in my 10D, but
I haven't tried to remove them.
Good luck!

Don't know about the Nikon, but the Canon Rebel XT has
a cleaning function (selectable from the menu) that
basically raises the mirror and opens the shutter
curtain for you to blow away alien particles.
Its just like a photo in bulb, so if the Nikon allows
to shoot without the lens, maybe that would be the way
yo go. I suppose he should use a rubber blower, since
water in his breath could result in nasty
side-effects.
Whatever he does, JUST BLOW and do not touch the
sensor.
HTH.
