Seriously, you are claiming that network latency and a delayed response to click events is a GOOD thing because it lets you fix mistakes that you made? Sorry, that is not how you design a product/feature.
The problem you are mentioning has also been solved by Google. In Ice Cream Sandwich when you click on a link that is close together with others, it will magnify the area to make it very clear which link you want to click. This is a solution to your mis-clicks - not a latency delay on every click so that you can fix it if you clicked wrong...
