My perspective is considerably different. I live in the "Silicon Valley" area of California (a little-known area of the Colonies!), and would welcome the concept of a fractional ownership scenario - not for corporate pax use, but for *private pilots* that can't really afford to buy (for instance) an R44 by themselves, but would like the opportunity for some sort of shared ownership of a nice helo that can carry more than 2 people.
I'm thinking of a 1/10 ownership setup - the buy-in is almost 8^) affordable, and the maintenance/overhaul costs would be spread over a considerable number of pockets.
I'm not sure if that's what you were asking for, but this is what I think of when I think about Fractional Helicopter Ownership.
