user is not permitted access to mysql configuration, so user cannot make a replication database.
if you are a databases administrator, u can create replication database.
i think, u make a coding that if u manipulation database, u should insert/update/delete to other database.
example : u have database_1 on host1.mysql.uk and database_2 on host2.mysql.org
u make coding where u your program connect to host1.mysql.uk & host2.mysql.org.
if u manipulate your data, each database must be manipulated too.
u should save to innodb (not myISAM) , why ??
because you must use procedure / transaction (commit, rollback)
