Create a model which represents all top-level items and, potentially, one expanded trip as a flat list. Pass down roles to the source model and let the source model handle that. We'll have to do some ifdef-ery, but so be it. Additionally, compile the base model on mobile as well. This contains a couple of hacks to make things compile at all.
