I don't see big conceptual obstacles to making a network stack itself be able to package up the internal state of a TCP or even SSL connection, and hand it off to another computer over a LAN, so that you could have graceful turnover of live connections. They could even cross-update info about the connection for hardware failover. I woder if (e.g.) Erlang OTP already does something like that. I worked on a device with such a feature a while back, based on very special purpose hardware and software and a special (hardware) communication bus for the purpose, but with some careful coding it can probably be done with stock hardware and ethernet. -- http://mail.python.org/mailman/listinfo/python-list
