What's up with VoIP demand???

So, the graph below is a pretty fascinating one that we were discussing in our board meeting last week. Google search volume for VoIP from '04 through the end of '06. Surprising, isn't it? Maybe we're on the early part of the Gartner hype curve, but I'd have though we were there 2 years back.

I should also add it's a particularly sucky graph when you were preparing your '06 growth projections for your VC right about point 'C'.
