Then I'd get caught. "jonlind.intergram.com" takes you to a "mock up" of the corporate website that I (and my boss) use to test new ideas and make changes to the website before we put it up for the world to see. If my boss went to "jonlind.intergram.com" and saw XRoads instead of the corporate site mock up, he might not be happy.
To "hide" it, I use port 8080. There's not much likelyhood of him thinking "gee, I wonder if Jon is doing something sneaky with port 8080?"
Anyway, your guy may not be crummy, but this is not a unique problem and having port 8080 open poses no threat to the security of the network, so it might as well be there for you to use.
