These commits add support for TileStream-hosted web tile sources to route-me. The header has a bit more info, but basically, you can get info about tiles hosted on a TileStream instance via its API, then initialize a small dictionary with that info, create an RMTileStreamSource tile source, and use that with route-me, similar to other web-hosted tile sources.
