Looking at 'tech sharing' I think that historically it was VERY limited in scope.
Without having ever studying the question, I would say you are probably right on this: transfer of military technologies was limited in scope (and still is).
Massive transfer of technology within the game would thus clearly be, per see, unhistorical...
On the other hand, the research model used in HoI is also quite unrealistic. While the technology tree is actually quite nicely done (even more so when using C.O.R.E.), the idea that a massive use of IC has to be used to make any kind of technological progress is completely out of whack ,or, at the least, the balance between production costs, supply (and maintenance) costs and research costs is completely wrong...
At the same time, there should also be some sort of “discount” in research costs, for technologies that have already been discovered and implemented by others...
End result: the technological gap between major and minor nations doesn’t stop growing, from something quite realistic at the start –because such a gap was existing- to something really excessive towards the end of the game.
This, in turn, makes minor allies more of a liabilities than an asset, at least past 1940 or so, and remove almost most interest from the already limited diplomatic element of the game...
For a human player, the solution is to engage into some regular technology sharing with its minor allies, to turn them into something a little bit less fragile. That solution works quite well with the game as it stands. Unfortunately,
- It means one have to remember to go into a round of “tech sharing” every 7 game-days, which fast become really tedious since the ergonomics of the game are so great...

- It puts the AI at an even bigger disadvantage against a human player, since said AI will not beef its allies in the same way.
All of this to say I think that whether or not those technology transfer where, per see, reaslistc or not should necessarily be what matters. I see it as a choice between:
- ”Realistic” technology sharing only, with “unrealistic” weak minor countries; or
- ”Unrealistic” technology sharing, with minor countries of a more “realistic” strength.
... knowing that none of those are really fully satisfactory, and that other issues should also comes under consideration (the most important being play balance).

I have created (am creating) about 100+ events dealing with tech sharing (new events, plus replacements) that are more 'generic' and are based also upon historic plausibility.
Would England waste time giving technology to Tibet? I don't think so, so why waste time/effort on them?
What we have to look at are the key nations. The key minor allies that were either supplied with equipment, or would have been should they have joined a particular side. These are mainly European nations.
I agree that Tibet should be left out of this, along, I would guess, with other Asian minors.
On the other hand, most –if not all- European nations should be included, so as to avoid that they fall hopelessly behind... and, I guess, most of American minors should be too...
That still leaves us with quite a bunch of countries...

With just a few events, trading limited technology, you can get minor nations up to par regardless of the side that they join, and without loads of events (so it is less leading than the current tech sharing that aid nations only if you follow history, i.e. Bulgaria only gets tech if they join the Germans, but nothing if they join the Soviets). Tech sharing/selling really is limited in scope, and can be simply applied if done well.
There is an existing automatic tech sharing system in place between allies. What we just need to do is to provide key technologies (tanks, planes, guns) instead of random techs.
Tech sharing under specific circumstances representing historic or plausible (i.e., what if nation X joined alliance Y instead of alliance Z) that provide limited and specialized technology is really the best option.
The technology packages to be traded should include, I think:
- Most Infantry technologies, including Artillery technologies relevant to infantry units;
- Some (i.e. when they really become obsolete for the major power) Tank, and Aircraft technologies, and related Artillery technologies;
- For potential naval powers only, some Marine and Submarine technologies.
Electronics,
Nuclear and
Rockets should probably left completely out. I would also leave most
Doctrines out (unless they are required as prerequisites for something that should be shared, maybe, or maybe the most basic ones when the major power is getting really far ahead?). I am less sure about what to do with
Production...
Those tech sharing events should be triggered by the technology level of the main allied major power...
