Yu Suzuki isn't making Shenmue III (see Polygon interview) and he shouldn't be with YS.NET. They aren't big enough to handle the project. If anything, Yu Suzuki needs to show big publishers that they can handle games that fans are willing to buy.
If Yu Suzuki is thinking of starting a Kickstarter or other sort of crowd sourcing project, I think he should start with a console game like Keiji Inafune did with Mighty No.9. He already paid 4x the developement from fans and is coming to Linux, Windows, 3DS, OS X, PS3, PS4, Vita, Wii U, 360, and Xbone.
The funny thing is, Yu Suzuki's biggest money makers where arcade games and the PSN/XBLA market eats those types of games like hot wings, with licking fingers and all.
I don't think you understand how many people at SEGA worked on the Shenmue project...
