DRBD? I mean, essentially what you are doing is slaving the second
system off of the first and a lot of the Linux/Unix HA tools would apply.

Or you could setup the 2nd server's working copy to automatically update
from the SVN repository as needed (svn update). Bonus points if you
write a post-commit wrapper script that triggers the process by using
the post-commit e-mails.

(Essentially you would have a mail queue to accept the notification.
Parse it to find out what files/folders changed, then have the 2nd
machine do update commands on just those files/folders to get the latest
versions. That could be very close to real-time.)
