Sorry, I should have said - the POD is Franz Ferdinand lives, and *WW1 ends up running 1915-17 with a CP victory, after which the Netherlands falls into German orbit. They may or may not get occupied by Japan later - but the Netherlands will get them back, and will probably crack down harder on independence under German pressure, which may result in a 'divide and conquer' approach that causes an ethnic/religious breakup.
If that's the POD... then so many things change. I think that 1917 is much too early for any independence movement, since the European nations were still strong enough to hold on to their colonies as well as take others. Of course the reason why colonies gained independence was because of the weakness of all the nations after WWII.
This also means that many of the intellectual leaders of Indonesia are butterflied away / change. Sukarno was born in 1901, and thus wouldn't be old enough. However there are two main groups that are still strong: The
Sarekat Islam(not an Islamic movement despite the name, they were more nationalist), and the PKI, or the Communist Party of Indonesia, which was created by an exiled Dutch politician.
Oh, another thing is that without Japanese occupation in World War 2, there will be a considerably larger Indo population, but nothing to the level of being a majority. There probably won't be any "Hong Kong's" but more like a few "Aruba's"
Basically, I want to explore what it would be like for Indonesia to be treated as its own region, like say, Central America, and not a monolithic block, and am willing to arrange events to get it so.
As it should be since the Malay archipelago, or
Nusantara 
o) as the locals call it, is very diverse.
I think as far as economic outcomes go it would be decidedly mixed - some places are likely to become just like Subsaharan Africa but others are likely to turn into tigers (any suggestions on likely candidates, BTW?)
I don't see any region becoming as bad as Sub-Saharan Africa, but "Bolivia-like" would probably be as bad as it gets. The island of Java might be worse due to the HUGE population there. I think places in Borneo could become as successful as the Persian Gulf states - it has a small population with oil waiting to be discovered at the time.
Sulawesi I see as the second worst-off place after Java, even though that's where I'm from, I won't be biased. Since pretty much everyone there besides the Christians in the central regions is pretty radical I'm afraid there just might be some genocidal tendencies from the Darul Islam groups there.
Nusa Tenggara (the smaller islands in the south-east) I can see being the Antilles of the east, rivaling the Carribean for tourists. And West New Guinea also is a potential tourist's paradise, if they go the way of Surinam and not that their neighbor Papua New Guinea.
