...we don't think we should have to pay for a "business process management" platform or implement "service orientation" so that future propositions that might come along have lower costs. If you want to build out "cool" architecture, you must find your own way to fund the bits and pieces that you need, rather than loading us up with costs."

Such is the dilemma of the way computer systems are designed and built in the corporate environment. An effective architect in a corporate environment needs to be forward thinking, yet practical and aware of cost and time pressures that their "customer" faces.
In my experience, effective architecture involves laying out a roadmap for technology choices, integration platforms, services orientation, etc, etc, and then spending a significant amount of time lobbying business users, other IT stakeholders, project and program boards, and C-level management for endorsement of that architectural roadmap.
It's a game of two steps forward, one step backwards, two steps forward. Some business systems projects will still need to go tactical, but as long as they go tactical with the support and understanding of the architects, then plans can be put in place to bring those systems back onto the architectural roadmap when the funding and/or time allows.
