I've recently encountered a product on WinNT, named Convoy and I am
wondering if there is anything at all like this for FreeBSD... I'll
explain.

It basically is a way of 2 machines and 2/4 network cards sharing one
IP address. They talk to each other (via MAC I belive) and also talk
to the router which they are connected to via the network, answering
ARP requests in a kind of you-me order.

If one server crashes then the other one takes over regardless.

Now; FreeBSD has never - in over a year now of using it crashed for me
:).... but as a service to our customers we do boast high levels of
redundancy - You get the picture.... so basically is there any kind of
sharing system like this for FreeBSD ? Round-Robin DNS is not the
answer - if we take one server offline then every 2nd user gets a duff
connection.

Any suggestions most appreciated... thanks.
