I suspect that a fundamental problem with the issue of reuse is at the business level. One reason applications have evolved as silos is because at the human organisational level, silos are a natural order of work in a big organisation. For example, a common view of the customer is rare. A reason why CRM is not used as much as it should be is that most employees think it pertains solely to sales and marketing. It doesn't of course, Customer Relationship Management should apply to anyone who deals with customers. Compartmentalisation in IT is often a reflection and consequence of compartmentalisation at the human/business level. Ever known a big company with excellent internal communications??
