Ok, awesome! I guess if its possible in MySQL 5, thats the way to go for me :). I will purchase that book, think it will help a lot!

Ok iisbum, you say all db updates should go to the master - how does the slave know when the master is down - just check if connection cannot be made? And how would I get the master to first of all get updated details from slave when back up without going online straight away receiving data? (to prevent 2 semi-different db's?)
