SaaS implementation

A new genre of service providers is emerging - SaaS service providers.

Here's a link about the same - Bluewolf, with experience in SaaS implementation have taken over as the pioneers. Salesforce.com has a consulting team - however, Bluewolf does implementations in many places as their services are cheaper. They can execute it and stay competitive due to economies of scale and scope. Now, joining Google for Google Enterprise Apps will help them quite a bit. Definitely, Bluewolf is at quite a bit of risk if they dont broker the contracts correctly with the end client or the service providers.

Will eSCM apply here? - both in case of CL and SP? Should it apply here?
As per me, the answer is yes - if you have a different point of you then you and I must talk ! :)
