You are technically correct, but I suspect your use case is going to be 
applicable only for a small group of users who are also developers.

/usr/bin/open is the command-line interface to the LaunchServices API, 
which is supposed to handle all this. I am not aware of any clean way to 
query Safari's preferences to determine the default browser without 
groveling through plist files, or perhaps AppleScript.

(Looking on the web, I see your openbrowser script does exactly 
that--grinds through plist files via Perl--but that introduces an 
additional dependency. I'd suggest that using a system-bundled tool is 
almost always better. It's certainly simpler.)
