ok lets break it down .. from your post -> "(limited use I might add). "
what do you mean by this? are you saying that some functionality is lacking? and if yes, what?
D-Nice is a calibrator and since he's a professional it's part of his job not to discuss certain things that could potentially lead to a set not working properly. In addition to probably alienating some of his contacts, in our current culture some joker would fry their set and then sue him for telling them how to hack the service menu. You'll notice on all cell phone/electronics/etc... modding sites the posters are anonymous. Not so here. He's upfront about who he is and what he does and he doesn't have layers of internet cloud to hide behind.
He's done an enormous amount for the avs community and his answers can sometimes be a little circuitous, but part of that is that he tends to be a little guarded to avoid saying things that are taken out of context and to avoid people blaming him when they do something stupid or make a choice they're unhappy with.
Based on your postings, you seem to be the type who if you fried your set would then blame D-Nice for providing you information so it's completely understandable to me why he wouldn't want to do that.
And you really should reread both your and his posts again. D-Nice is almost never wrong and in this case he wasn't telling you that firmware hacking would not yield the results you want. He was indicating you can more easily get the same effect by having the patch applied should you choose to (although I'm still not clear on the warranty implications of getting the patch applied... it seems that it may be a touchy topic). The gist of what he's saying is that you paid a fair chunk of money for a plasma, there's already a relatively cheap way to get the same effect should you decide you want it and are aware of the implications of getting the patch applied, and you are much less likely to fry something by applying the patch.
If you want to go ahead and work on an alternative, more power to you. I'm a big fan of modding myself, but it's not a cheap tv, not easy to replace, and the risk of damaging it is significantly more than with other electronics. Also, be advised that there is often variation within a single product line, sometimes having actually different firmwares or firmware lines needed to run them. What works on your set may fry someone else's and what works on someone else's may fry yours. The patch is something that to my understanding is minimally intrusive and designed with a full understanding of how the sets normally work. I don't think you're likely to get any calibrators or other pros to divulge trade secrets about the workings of Pioneer displays over the internet, but if you search around for other people who've done similar to what you've done you may be able to find other people to work with if you have a mind to.
