It seems to me like most bandwidth-critical businesses also require a datacenter anyway, and while fast to-the-home internet may enable the delivery of innovative technology (like high-definition gaming in the cloud) a fast connection to the home isn't necessary for the creation.
With that being said I do appreciate the concept: if building high-speed fiber can attract entrepreneurs (regardless of if it actually helps them), the incentive for municipalities to encourage high-speed buildout grows.
