LOL, this isn't correct either: if it's not a file scheme, it doesn't 
work (just returns NO). Now that was some great smartassing. :-)

Nah, that shouldn't be the way to do it. Back in the OPENSTEP days when 
NSWorkspace didn't have an openURL: method, one used to call OmniWeb's 
Open URL service, which is somewhat similar to the simplistic 
NSWebBrowser default approach. Nowadays the correct thing to do™ would 
be to resemble an approach that OS X or KDE (probably GNOME, too) 
implement, which is to refer to something like the InternetConfig 
(buried in OS X's CoreServices) and let this handle the appropriate 
scheme (if it can handle it). After all, these schemes can be a variety 
of protocols, most likeley HTTP but also FTP and NEWS. 'NSWebBrowser' 
is probably too simplistic. Whether this configuration is in the scope 
of Preferences.app or GWorkspace.app I'm not sure (I tend to think the 
latter).

Then again, on non-Unixes (Win32) it's probably not clear whether the 
underlying infrastructure (Probably some Registry keys) would have to 
be used.

Just my thoughts, still no solutions, duh.

Cheers,
