If baseball starts a video review, how could it be done without interrupting the flow of the game too much?

Jim Joyce, veteran umpire, botched a call yesterday that cost Armando Galaraga a perfect game. The was running quickly and was called safe, but on replay was clearly out by a step. Joyce admitted his mistake and apologized to Galaraga but the damage is done—he won’t have the 21st perfect game on record. This has renewed interest in an expanded replay rule, but there are fears that it will interrupt and damage the integrity of the game. What do you fellow baseball fans think?

Personally, I’m opposed to an expanded video replay rule, but I’m a purist.
