Breaching the corporate firewall

Forrester's Q3 2011 Mobile Collaboration report compares different approaches that vendors are adopting to get their products/services into the corporation.  2 comments stood out for me:

I'm not sure how many CIOs would go along with the notion that client/server achitectures are dead.  I tend to go along with Forrester on this one but there will be a lot of wailing and nashing of teeth before it is more widely accepted.

This is a key point with many of the services covered in the report.  Demand from employees, clients and suppliers will erode CIO resistance to cloud solutions as many are already being used in the corporation even if managers are not aware of it.
