Does Enterprise Apps on a Box make sense?

In OOW 2009, Larry Ellison presented a powerful case of DB on a Box Machine. He demonstrated Exadata2 for almost more than half of his presentation time. It is a good story to make customer up and running quickly and saving from chasing different vendors. However, he presented it in the context of Database. Wouldn't the same model make sense for Apps too? It's is kind of different than the current momentum to SaaS and Cloud. But installing, configuring, tuning and setting up enterprise Apps is a time consuming process involving multiple vendors and skills. If that can be reduced by this Apps on A Box model, would it be better?
