Pony Express in the Frontier

I just read the chronocom article from SFMan, which pretty much invalidates this idea unless you play the game in an era before the development of subspace com.<br /><br />But, I had fun developing it so I'll throw it out there anyhow.  It is basically a spaceship based takeoff on the pony express.  A small ship one person (or possibly robotic) with a really big hard drive and really really big engines (giving the ship a huge ADF) sits at the edge of a system and recieves sublight message traffic.  The ship then accelerates to the fastest possible jump speed to the next system where it drops just out of the void, deposits the messages for that system, picks up new messages, and accelerates slightly, to re-enter the void on its way to the next system.  A network of these vessels would be in constant movement around the frontier delivering messages.<br /><br />The ship itself would be defended only by its speed and very short time in realspace.  Combined with the fact that it doesn't carry anything valuable, and it would be ahead of messages to intercept it, makes it a pretty low value target unless you were a terrorist purposefully trying to disrupt communications, or some such thing.
