Twitter Binding needed?

Most existing topics where Twitter is mentioned refer to the possibility of using the Twitter Action to send a message or notification on Twitter.

I am trying to do something different as I would like to read the tweets from existing Tweeter feeds, and trigger some actions if certain words appear on recent tweets. As I could not find any binding that provides this functionality, I tried to use to convert a Tweeter feed into RSS, and then use the Feed binding to consume the information. Unfortunately, the service often returns HTTP 500 and the Feed binding only seems to provide the latest entry, which is not sufficient for what I am trying to achieve.

Is there a good way to retrieve structured info from Twitter into openHAB or that would likely require a Twitter Binding to be developed?
