can traditional auction house searching be phased out with an addon?

someone told me you could use caching to store the item keys for every item you want to shop for to save time on search results. then, through the use of an automatic search function, you could shop for items as soon as the auction house is opened. my question is, how much faster would this be? you would still need the auction id and the price parameter for the addon to show items at or below that price. would this realistically be any faster than what trade skill master does?
