CE system does not have an native NetBios(SMB) protocol support ( as we
use in our messenger LanTalk XP ), it can be implemented in the
software, but it's a very hard work and no reason for developers.
NetBios is one of available protocols. Lan messengers can use other
protocols or self made protocol ( as in our LanTalk NET ). Currenlty we
have no CE client , but maybe do this later. There almost no market for
such product for CE.
