SMB not fit for SOA?

During a training class I was leading today, a very interesting question came up which is "All this SOA stuff we have been talking about today is great for a large company but seems to be overkill for the SMB (Small / Medium Business). Since SMB makes up a much larger percentage of the business world then traditional business, why should we care?".

Well one way to look at the problem is that services are permeating the cloud computing space, in fact last week's SOA Symposium co-hosted a Cloud Computer Conference. Cloud computing is becoming a game-changer for SMB in providing a variety of tooling from productivity (documents, email, etc.) to CRM (i.e. Saleforce.com) to HR (i.e. Workday) to Infrastructure (i.e. Amazon/Azure). The one common aspect in these is the ability to interact using service APIs and thus the need for SMB to be adept at service consumption and composition.
