 However, as I said, NSWorkspace (in GNUstep) doesn't implement

Would anyone be willing to implement this properly under GNUstep?

This isn't entirely correct (but isn't entirely wrong either).

NSWorkspace -openURL: checks whether the given argument is a file, and
if it is, tries to open it (or notifies the appropriate application to
open it). If it is a url, it returns NO.

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. :-)

In this case, the example services should kick in, which try to launch
'mozilla', which isn't necessarily installed. However, the example
services will check whether 'NSWebBrowser' is set and use the specified
web browser instead of 'mozilla'.

In most cases this should work fine, though I'm not entirely convinced
that this is the way it should be implemented.

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.
