  No need to be at all; Olympus did it easily with the OM-4t and 3t.
  Actually it's pretty simple, like a flashbulb.
  You've seen Olympus' redeye reduction in their p&s cameras? It's often
called flutterflash, rapidly-strobing. Olympus took it further with the
F280 flash.
  The flash starts high-frequency pulsing, the shutter runs _up to 1/2000_,
then the flash stops. Olympus uses the TTL circuit to set the intensity of
the pulse, for TTL autoflash. Below 1/60 it acts an an ordinary electronic
flash.
  The big drawback is that power is rather low in that fast-synch mode
compared to ordinary auto, but it's far better than nothing and fill flash
at high speeds can be pretty useful.
