翻译：in a nutshell,that's what's we are doing
前后文是：Zennstrom once spent an hour detailing Skype's business plan to two U.S. venture capitalists, summing up: "In a nutshell, that's what we're doing." Friis, who had remained silent almost the entire meeting, said, "A very, very long nutshell." His customary uniform-jeans, sweater, backpack-contrasts with Zennstrom's suit and rumpled shirt. He's the innovator who doesn't have time for business niceties.
