Just a very quick note on this post - we're head long into completing development of our initial product and have had some great commitments from our beta-test companies so it's obviously a very exciting time for us. Will have a load of updates once we've done the release of the product.
In the meantime, checkout the prototype Twitter streaming widget - we'll be making this available as part of our product offering for people to plug into their site. At the moment the prototype is just hard-coded to "obama" but the final product will be configurable to any number of subjects in real-time. Check it out and if you're interested give us a shout about using it (just click "activate" to kick off the stream).
