shots, but an electronic shutter, like digicams.

That's right. With some third party flashes the D70 will even
sync at all shutter speeds down to 1/8000. (I've seen this
in practice with a Metz flash).

Me too (with a tiny and ancient Starblitz). But it does require a
Don't-try-this-at-home warning that the manual warns that "Negative
voltages or voltages over 250 volts applied to the accessory shoe could
not only prevent normal operation, but damage the sync circuitry of the
camera or the flash"

I assume any single pin flash unit (plus some with extra pins which
manage to avoid sending or receiving the wrong signals to or from the
camera) would be able to perform this trick, but you have to know that
the flash won't exceed that 250v limit, or at least have protection
against excessive voltage.

Also, I noticed underexposure (just perceptible at 1/4000, pronounced
(about 1/2 to 2/3 of a stop) at 1/8000), presumably because the
electronic shutter closed before the flash had finished firing, and
that may be one of the reasons why Nikon don't allow their own flashes
to exceed the 1/500 speed limit.

Treat anger like gold. Spend it wisely or not at all.

Not 100% sure on the D70, but I was told by someone in Olympus's training
section that the E-1 can synch at any speed - it does this by telling the
flashgun what shutter speed is in use. If the shutter is fasterfaster than
the normal synch speed (ie, speeds where the 2nd curtain starts closing
before the first curtain has finished opening) the flashgun holds it's flash
on for the entire duration of the shutter. Presumably this function only
works with Olympus flashguns, and i'm not sure what the conventional synch
speed is with the E1. I wonder if the D70 is doing something similar??

According to the link above the sync speed of the D70 is 1/500.

Can anyone confirm this?

If so I would guess since the curtain travel is a bit shorter that they
could shorten the time... but 1/500 is a real improvoment for this class
of SLR... or any SLR (not counting leaf shuttered SLR lenses). The only
other SLR's at near this speed are the F5 and Maxxum 9 (both at 1/300).

Is it limited to the built in flash ... does it apply to attached
speedlights?

That's High Speed Sync which is a different beast altogether.

I'm referring to simple "traditional" sync speed (X-sync) where
the shutter curtain is wide open at the time the flash fires.

Several camera systems have HighSpeedSync (Minolta, Nikon, Canon,
Pentax... prob'y more).

However for use with studio strobes, HSS is useless.

No Alan, it's not HSS. The flashlights mentioned certainly do
not support HSS. This is real thing.

Of course, you need some experimentation and adjustments
to get correct exposures at faster shutter speeds, but this
is quickly done with a digital SLR.

I'll take your word for it ... however this implies that a
"software" shutter is used rather than mechanical (whether or not
is is electronically controlled).

And to put a point on it ... I don't see how this would work with
studio strobes (except haphazardly).

FWIW, the D2H normally syncs to 1/250. However, in programmed auto and
aperture-priority auto modes, shutter speed will automatically be set to
values between 1/60 to 1/8000 sec when using the attached SB800 flash and
having the camera set to Auto FP High-Speed Sync. The combination is what
Nikon calls CLS or their Creative Lighting System. Works great.

Won't work with studio strobes beyond 1/250 methinks ... that's
really my interest in regards to the first posting.
