Several browsers allow to open a URL in a new tab or window directly from the command-line, e.g. Firefox has
-new-tab URL and
-new-window URL just to name a few. This will allow scripts (AppleScript, shell, xbar, ...) to open a website via such command-line interface.
Extra thought: Currently, the Orion binary in the folder /Applications/Orion.app/Contents/MacOS doesn't seem to provide any help or list of available options. It would be useful if such options, once implemented, would become visible via
--help or similarly named option.
