I don’t know why I digress – almost everything my teams do is related to high-throughput High Availability and Systems Integration apps written in server-side Java. But, our company does pride itself on providing super elegant GUIs on top of the enterprise business tier – we feel its what makes us different and more valuable than most other consulting shops. Plus, its also nice to occasionally dip into other languages to keep on your toes.
And although I’m not at liberty to show this product (yet) due to contractual restrictions, I found an app named Meebo that is based on the same principles. Although our app is much larger (millions of users directly supported, etc) and in an entirely different vertical domain the front-end client technologies are similar. Check it out, they’ve done a nice job.
