TweetDeck Modification

I believe that twitter processes and distributes news faster than other mediums. I use tweetdeck, and want to exploit some of its ability, in my custom way. Here's what I envision: a column for each symbol that I care about, let's use $GOOG for example. I want a column that contains tweets from the equity service I mentioned in an earlier post, and a *filter* that allows me to keyword filter news tweets. I want to see the reaction of $GOOG to news releases, instantaneously. I do realize that this is the opposite of efficient market thought, but I've seen evidence of this occurring (and believe it can be exploited). I want news fast and if I were a swing trader, I could react instantaneously to my perception of the news on the equity (or derivative) that I'm monitoring. More advanced custom filtering would also be useful, can you say text mining (sounds like fun)?!
