How is a new carbon frame developed?

How difficult is it to develop a new carbon frame, like the Cervelo Soloist Carbon? Frame dynamics – ie ride characteristics and fit – and geometry are pretty much old hat.

Watching the tour got me to thinking … as just about every bike in the race had a carbon frame. I think Fassa Bortolo was the only team riding non-carbon bikes.
