Passing data between the web to an Intranet

Has anyone ever simply tried to pass information direct from the web into a secure Intranet mysql DB rather than to a web DB? I am thinking down one of three lines. 1) I use PHP to send an email with the data in it and update our internal DB manually (the worst case) 2) I use PHP which takes data, sends it as an email, puts it into a form which then automatically updates our internal network (interesting idea but I have no clue if it can be done ;o) 3) I use some sort of synchronisation so every time the web DB is updated our internal one is also updated (ideal). I would welcome any other ideas or solutions. Does mysql have any replication or synchronisation functions? I am told Oracle has but haven't seen this or heard of this with mysql.
