We could also use the isomorphism of wares to just have the raceway formula itself mount the desired thing into the desire place, and thus have caching disappear in a puff of smoke as it's handled automatically by the container layer... but our scripts haven't reached quite that level of genericism yet (and that whole theory will also be a helluva easier to partake of once we get a raceway rebuilt with the v200 repeatr and rio stuff...).
