I have thought about this myself, but our clients usually only frequent locations with good broadband connections, so thats not really an issue for us. However, it would be ok to know more about what one could expect if you suddenly had a client on such a low-speed connection. > This would need some testing in real environment, or a comment by someone > who knows the protocol that is used between the daemons. > > -- - Christopher ------------------------------------------------------------------------- Take Surveys.
