Something overlooked in the previous responses is the change in the default database from DB2 to ProsgreSQL (which VMware has contributed to SIGNIFICANTLY in the recent years, i.e. vFabric https://www.vmware.com/products/application-platform/vfabric-postgres/overview.html). This changes the whole scope of the "small systems" deployment since "arbitrary" and "feature restricted" licensing is no longer an issue.
OPINION: As VMware pushes vFabric "goodness" expect to see more robustness in PostgreSQL-based appliances.
