8080 is a well-known port that may be (probably will be) in-use on a developer or build system. I see that there's a mechanism to override this via a command-line flag, but I think it's preferable to use a different port from the start since I'm expecting we'll have to do this on the build system. We should either select a higher port that's not likely to be in-use, or randomly select a port at runtime and figure out a way to pass the port around to the following pieces of code that need it.
