I've just downloaded the errata sheet 80144a, which helpfully
explains that ES marked parts won't program with a vdd  >3 volts .
Thats my current programmer out the window for the moment then.

Not really.  First, this is a new part and the errata applies to the "ES"
version.  This stands for engineering samples.  Such early versions often
have a few strange problems.  Unless you are reasonably well connected,
you'll never see an ES chip.  Seconds, if you've got enough expertise with
PICs and electronics to get ES parts, modifying a programmer produce 3V
power instead of 5V shouldn't be a big deal for you.

I got samples of 18F2320-I/SP and 18F4320-I/P a couple of
months ago, none of these are marked "ES". And the
errata sheet is marked "2002" (no date).
So this is probably no big deal (as Olin expected).
