    You can do this in Linux with Julian Anasatov's Dead Gateway Detection
    kernel patches. http://www.ssi.bg/~ja/#routes. Specifically, you will
    want to peruse http://www.ssi.bg/~ja/nano.txt and
    http://www.ssi.bg/~ja/dgd-usage.txt.

    Using this technique you will very effectively be able to load-balance large
    number of connections. The solution will also detect when a gateway is dead
    and fail it over appropriately.

    Fine!

    Speed is not important here. You just need something fast enough to route
    your packets. A pentium 233 with 32 megs of ram and a decent NIC should be
    able to route > 20mbit of traffic.
