I've gone over the developer's, administrator's and user's guides for Windows Desktop Search, but couldn't find an answer, so I figured I'd abuse the fact that there's a PM lurking around here and throw the question out here. 
Is there a way to brand an instalaltion of WDS that is deployed in my organization? Using the IEAK, I can brand an IE deployment with custom logos and such, and I wonder if it can be done for WDS as well. The basic needs would be 1) adding a logo, and 2) the ability to add, in addition to the Search Desktop and Search Web buttons, a third "Enterprise Search" button that launches IE with my enterprise search app of choice.
Is this possible with WDS 4.0?
