Mobile strategy question-

How have large corporations, or mobile solutions vendors, addressed mobile app needs for distributed independent sales offices? (Think network of real estate, insurance offices, etc) Is it possible to build one app, one set of requirements, but brand the app diffferently when someone activates it? So, for example, a customer in Topeka downloads the app, and activates it, he sees the branding/logo for his local independent agent, while a customer in Miami sees information for a different agent? Can't base it on geoIP, because there can be many such agents in Miami, each with their own office name/brand. Maybe even two agents in the same building. It would need to be triggered by the unique customer account login, I would think.

I'm interested if anyone knows mobile development companies that have built solutions dealing with this issue, or if there are any related case studies.
