There's no real distinction in HTTP; either way you're expecting to
receive a resource (for example, a web page).  The colon is used to
specify the port to connect to, and defaults to ":80" (the reserved HTTP
port) if ommitted, which it usually is.  We could set the zigzag server
up to use port 80 but would want to check if it was already in use by
another web server first!  This would also prevent users from starting
another web server on the normal port.

If the "desktop filey-looking thing" represents a URL, as with "Internet
Shortcuts" in Windows 95+, yes.  Alternatively you could have an HTML
document which contains a META tag redirecting the user to the URL for the
zigzag server.  Or the zigzag server could start a copy of your preferred
web browser and point it at the correct address.  This approach has the
additional benefit that it allows us to pick a port number at runtime.
