Well, after some more research, it appears that I have found much conflicting information concerning Mobil1 and their user of Group III vs. Group IV base stock. All the "official" reading states that they do indeed use a Group IV ... foot in mouth 
Mobil is a huge producer of Group III base stocks. What are they using it on? It looks like they are using it for Mobil 5000. It also looks like Mobil 7500 is a blend of Group III and about 15% to 20% Group IV, making 7500 a true "synthetic blend" instead of a "pretend" blend because it has some Goupr II+ or Group III in it.
But engine oil is not really the topic of this thread.

Life of trans;
1) Low mileage trans (less than 25k miles) bought from LKQ Auto Parts of Northern California
2) Sent to Terry for Upgrade/Quaife
3) Ran Ford "Honey" for first 500 miles, flushed
4) Ran Ford "Honey" for next 500 miles, flushed
5a) Ran MTL for rest of life, flushed every 15k miles (+/- 1k miles)
5b) Has been flushed/filled with MTL 4 times (approximately at 60K,75k,90k,105k)
6) Car is currently at 109k miles.
7) Only 5 passes down the 1/4 mile, never autocrossed, lots of spirited mountain driving.

Jim.
I don't have any problem with this summary of yours. I have no problem saying to err on the side of caution and not use Redline MTL. That's just saying there has been a question on the product but nothing conclusive.
Terry: I don't doubt your observations or your desire to use the best material. I'm guessing you may want to go ahead and build up a small file of pictures for comparison purposes on ATB equiped diffs and the fluid they run. Hopefully you will minimize the number of variables in the comparison. This will be more compelling when you post that information rather than hearing it 3rd hand from some guy whose credibility is unknown to us.
For myself, I won't bash the redline product only because I observed quite different results from using it. If I hadn't had personal experience from using it I would never have posted anything about it. I'm not going to push it as a product, but I will post that I had great shift feel and apparently good results. I don't know what fluid I will use next. Since I am apparently almost the only one now who has had good results with it and willing to talk about it then I will quit this fight and just leave it at that. I don't know where all the other people are now who used to 'love' it. I use my brain before I do something and if I screw up then it is my problem. No blind following from me, no blaming, and no sucking up.

That would be a good sample if you send the oil in for analysis

But you have had a Quiafe. A much different animal than the stock diff. The problems lie in build up under the planet gears. I'm sure a tranny using MTL with an LSD will hold up. Is it the healthiest though? Is it tempered on any of the splines, oxidation on the LSD?

I went back and took a hard look at the page in the Ford Chemical catalog that describes Ford Honey and found that it does indeed call it a 75W90 oil, not just that it can be used for a 75W90 gear oil.
It does not say that it is a GL4 oil though, just that it can be used wherever a 75W90 GL 3/4 gear oil is specified. So maybe it isn't quite GL4, or maybe it is GL4 but just not tested to validate it.
What is even more interesting is that it is clear that the Castrol SMX-S is published to be 75W85. It is interesting that in a Ford bottle it is a 75W90, but in a Castrol bottle it is a 75W85. Yes, I have verified that it is the same product, but my information source requires confidentiality.
I still have the opinion that any high quality manual transmission oil that is as thin as ATF or as heavy as 75W90 should work fine in this transmission. So why didn't Red Line's product hold up?

Why can't everyone in America have this attitude.  I think Jim summed up this thread the best.
