I know that 3Com hubs can do that, and someone told me that
HP has this feature too. But I don't think there's encryption
involved. Box just learns MAC addresses behind each host. Frame goes
in clear to real recipient, but others get just random bits.
(You have to send something to other hosts, because in ethernet
ethernet only one host can send in one time).
