Active/Active (or master/master instead of master/slave) MySQL replication has been around for a while now. You could also avoid the proxy situation by using a simple round robin DNS. Since it's master/master it doesn't matter which one you connect to. If you're using persistent connections, then obviously that negates the round robin DNS a bit. I gotta throw my $.02 with alarms.php though. I don't have as many concurrent logins, but I have just as many accounts - and it just doesn't run good at all.
