Make Berskshire Hathaway stock priced in 1/100th unit instead of 1/10,000th unit and the stock price can go 100 times higher and you don't have to change the existing data feeds - which would be quite expensive. All you have to do is send everyone the message that this stock symbol is priced in 1/100 units instead of 1/10000. Seems to me this would be the least-intrusive solution.
