Transestherification swaps out the glycerol chain for an alcohol one w/i the molecular bond of the oil, which, like Keith said, makes it burn...or rather "explode under pressure" better than SVO. I believe in researching storage legality that BD must be treated as a Category 3 explosive, you won't find such a thing w/ SVO/WVO.
AFAIK this is why BD will run in several (high pressure) diesels where SVO, even w/ a preheater, performs poorly if at all.
Now, theoretically, because the idea of a diesel engine is that it uses pressure instead of a spark to cause the explosion w/i the cylinder, you *could* get one to operate on a *lot* of different fuels, but it isn't recommended.
And, furthermore, if reducing the viscosity of WVO was the primary goal of producing BD, there are significantly simpler, cheaper, and safer ways to do it than transestherification.
Just my 2 cents, I'm not a pro.
