Yes, if you consider that the way MacOSX does it is the correct way. Other 
thing is that how would you expect it to behave.

This is something I wanted and was asking for. I knew that there are some 
methods in -gui for doing the sutff and I just wanted them to be public. 
Thereis also a method -_connectApplication: in NSWorkspace.m, but it seems to 
be different from GSConnectApplication.

GSConnectApplication is good method, but it requires some NSPort and a NSDate 
to be passed. Would it be possible to create a simple wrapper fot that method 
which takes just one argument? like public gnustep extension method in 
NSWorkspace -listenerForApplication:(NSString *)name ?

Thanks,
