I think that is the wrong end you are looking. Try to use MySQL cluster 
and you can add servers as you wish on the fly. However, you need a lot 
of memory for each of these machines.

My road map of growing system is:
1. Two (more) Asterisk servers use the same mysql database (done) and 
share the same config files and temp area (e.g., wakeup) (planned via 
NFS as a quick solution, later to contribute that back to MySQL)
2. Add one (two) SER servers with round robinson DNS settings
3. Add multiple Mysql cluster to the existing Mysql machine
4. relocate a set of machines to another place


End will be, that the MySQL cluster becomes the heart of all!!! SER and 
Asterisk will become "slaves" of MySQL.
