It doesn't need any info from any table.

If the table prefix set in wp-config == $my_master_prefix : this is a  
Master.
If the table prefix set in wp-config != $my_master_prefix : this is a  
Slave.

Thus, $this_role doesn't need to be set by user.  Auto-detect! :)

Also -- it appears you hard-coded some variable data in the plugin.
