The issue is simply that the camera cannot handle the range of light from the darkest object to the lightest object. Moving the EV down 2 is simply going to change where the exposure gets lost. If you lower it enough to expose the water properly, a lot of the remaining image will be dark shadows and possible lose most of its definition.
As far as adding grads, you would need some sort of center spot grad or centered grad (do they make such things?) to work around the big bright spot in the middle. You need to use bracketed exposures and some post production to fix that.
Most of the rest of the image is very nicely exposed. Lovely photo overall.

I found out what "auto ev compensation" is:
- it works in Hyper-P and Tv mode (can work in Av)
- what it does: imagine, that you fixed Tv value to fast value (e.g., 1/8 ), and then you want to shoot in dark room. So when you half press shooter button, then camera changes Tv value to 'real' value (e.g., 2 sec). So if correct exposure cannot be taken, then camera automatically modifies Tv (or Av?) to get correct exposure.

As always, I guess someone will be willing pay the price to be the first kid on his block with the new toy.

Tried to delete my message... but too late again.
I have used a 1 meter extension on the cable that came with the K10D. That is all I have, but at least it makes moving around the laptop a little easier.

As a matter of interest do you know if there is a limit to the length of of USB2 extension cable which may be used when with the REMOTE Assistant Software and a K10D in this set up. ?
In general the limit should be about 5 meters for USB2 device. Although perhaps 3 meters or so is probably a safer guess at a reliable length.
You can also daisy-chain a limited numbers of hubs to get longer length but that is sort of a pain in the rear.
Any USB 2.0 compliant device should adhere to that.

When the shutter is released, does the green progress bar in the lower right of remote assistant show the image being transfered at all?
How about no the camera, does the LCD show the image or are images stored on the camera? Or are they stored on the hard drive anyway?
Try using the camera's shutter release button. Does it have the same effect? (It should work the same either via the computer or via the camera when connected).

Otherwise, I cannot think of any reason why the flash would not have fired.
Oddly, there does seem to be some inconsistency in functionality.
When the control flash (attached to the camera) is set to "not fire in wireless mode", it seems to fire anyway. I see no difference when I have only the control flash in use and have it set to fire in wireless and to not fire in wireless mode.
There is a definite difference when I have the remote flash active, so it is obvious that something isn't quite right.
Maybe just my perception, but the control flash also seems to fire its control signals with less power when in high speed flash mode than when in normal wireless mode. If that is true, it would be more critical that your remote flash be aimed in such a way that it will pick up the control flash reflections properly.
