+kfmexec is launched when the user wants to open a remote file with
+an application that only supports local files.
+
+For this it does the following:
+- downloads a remote file to a temp location
+- starts a 'local' application with that temp file as argument
+- wait fors application to be exited
+- if the modification time of the file is different from the original one,
+(because the file was modified) then it offers re-uploading the modified version.
+This is how you offer network transparency to apps that don't have it.
+
+BUT: with KUniqueApplication, this breaks, because the app returns at once,
+so we have no way to know when the user finished editing the file...
+
+Conclusion: if the application has network transparency built-in, it should
+put "%u" in its desktop file - and kfmexec isn't used -. If it doesn't, either
+it's a TDEApplication and kfmexec does its job, or it's a KUniqueApplication
+and... kfmexec can't see modifications to the file. Be warned.
+
+From Waldo: "The program doesn't return _at once_. It returns
+after "newInstance()" returns. So if you open the file there it will still work.
+(Or rename it)"
