I'm not exactly sure of what you are asking, Nick. I am certain the IWN sites in the National Capitol Region will have some inauguration related traffic, but are you wondering about hearing it from the Pacific Northwest? I doubt that there will be any traffic from DC showing up there, unless someone locally has a NCR talk group in their radio and has it affiliated to an IWN site near you.
The IWN is not set up as a simulcast system, and each site only carries traffic for the radios affiliated to that site. There are some CBP talk groups that can get broadcast to multiple sites that seem to be determined by what button the dispatcher pushes.
As for the FPS, you never know. The FPS MegaCenters can link channels and back up dispatching duties for each other. But again, I know of no specific reason to re-boradcast traffic from the DC area in the PNW region...
