This I don't think is possible, based on the reasons I gave for why two independent processes launched by the same user can communicate. Someone will correct me if this is wrong... A workaround could involve writing the data to a file that the two users could share, with flags being set to notify the receiver that the data is available. Probably opens up at least a few cans of worms though... Richard
