There's been quite a few suggestions along those very same lines, making the routes more passenger focused and special OS&C only commodities. The former has been brought up with Xoria who explained that OS&C work with luxury items and passengers in their routes, so things like pearls, furs and the like are all bundled together under the ID so to speak.
Eventually we'll be opening up into Gallia which should bring some interesting routes and RP conflicts, including a bit of unfriendly competition from EFL's liner division so lots of fun to be had there.
On the commodities front we currently have a couple of ideas, one is an OS&C only version of the VIP with slightly less cargo space (ideally) and another open commodity called baggage which is self explanitory. All of which is to come, naturally the more folks we have the easier and sooner it'll be done.
