Just wondering is it possible to query multiple databases for the same table with HyperDB ?
My idea is running multiple WP sites with This and setting up a "Central" Server.
Now if a user tries to log it it must check if the user is on the "central" database but, it must also check if it's on the site's local database, and if it's not i need to copy it over from the Central database to the local database, if that makes sense.
I managed to setup the master and slave now so users are running of a cetralized database, now i just need to find a way to get it copied to the local database and also check for user on local database ( Optional ). Any ideas or help would be greatly apreciated.
