Co-presence solution: Twitter 2.0

We are looking for a developer who totally understands co-presence. A developer who has analysed Twitter and can see the future: Twitter 2.0 We are not simply looking for a Twitter clone. The co-presence solution we want you to build is the next generation, but must maintain the simplicity of Twitter and have an open and extensible API. Please analyse twitter, jaiku and the other co-presence apps before submitting your bid and tell us what u think Twitter 2.0 would encompass. Please note, we are not looking for blanket responses with a list of all the projects you have done...we want you to think outside the box and give us a feel for why you are the folks who will get to work with us on this exciting project. Upon completion of this project we will own the IP developed so please don't bid if you are in the business of simply cloning multiple times. Note that this is the tip of the iceberg – we have a ton of other projects in the works! Good luck on your bidding and may the best developer shine thro.
