We are having some great success with our new PushBI and have updated our Server part of the product recently with some new features along with usability updates. Our PushBI Server provides data to our software clients but can also be used by other clients. An example is we have recently used SilverLight to access our server and provide a KPI Browser like you have in iTunes when you browse albums. Very cool.
