There is life after one project is announced. Banco de España -Spain's central bank- selected Microsoft for Target2 a couple of years ago.
The solution, built on top of Biztalk, is not very demanding from a functional or performance point of view, but is pretty critical -it handles cross-borders payments over 50K euros-.
I worked for that project for more than one year between 2006 and 2007, leave it on the testing phase, and now is up and running. That's one of the better feelings working on software.
The title, "Real artists ship", is a phrase from Steve Jobs. I like the phrase a lot and the story is sad but true :).
