Does anyone know of any non-ISP companies that have decided to multi-home? Is this a major trend for non-ISP companies running mission-critical applications on the Internet?

Yes, several. As far as I can see, yes. The question I'd ask would be why does it matter if an AS is "ISP" or "non-ISP"? The domain of clueful people is far and away NOT limited to the domain of ISP networkers. If an organization is sizeable enough and knows what it is doing, or can hire or rent someone who does, more power to them.
