We've used fake (part of the linux high availabilty project) before and it
works quite well:

    http://www.vergenet.net/linux/fake/

If the main server is not responsive, the backup server steals it's ip
address
and comes online almost instantly.

Never tried it with raq's, but I don't see why it wouldn't work there as
well.
The tricky part is keeping the data in sync, but depending on your needs,
you
can use things such as rsync, mysql server replication, or nfs.

Cheers,

Alex
