in reply to mirroring mySQL database

I think you are on the right track with your email the SQL statements idea, that way data only gets sent when there is data to send. Probably slightly more secure than FTP. The other methods suggested so far require more rights or access than you have. You could take your SQL convert to XML then back to SQL, but that would be extra work. You will need to do some sort of integrity/validity checking so someone doesn't email your program a "DELETE sales" command. PGP email may do it.
