I've been thinking about a possible solution:

The NbJavaCvsFileSystem has a method

public JavaCvsRuntimeCommand prepareCommand(FileSystemCommand command);

this method is used to add the runtime tab's subnode when a command is started to keep track of the 
command's progress.

Even though it returns JavaCvsRuntimeCommand, it's return value is usually ignored.
If you create a infrastructure for registering global listeners, this method is the place to hook 
the registered ones to the FileSystemCommand.

That's probably the "least-ressistance" approach I can think of.

Regards.
