What i would do to save you all the trouble is dedicate one server just to MySQL, and another one to serve page requests.
Then what do you do when the Mysql server is offline.. now you have two domains without a working forum..
rsync is ok for one way mirroring. But they mentioned using either domain.. And i'm going to assume that these two or more domains will be located on their own server.
Either using mysql's replication or even playing around with unison and see if that would do what your looking for. Unison is for making two-way updates, but again you would have the problem with the database files, depending on what database system you use.
Just some ideas..
