I would like to a create a script that could be used on anybody's website and they have the choice to make their database public or private. if the database is public it allows other site owners to connect to their database when thesite owner installs the script. for example

user 1 has a site that is public and has a randomly generated number used as the key.

user 2 is setting up a site and wants to use a already established database. they enter the the key and the database is shared.

when either site is updated, the database is updated.

If database is private, no key is generated, no1 except the original site can use the database.

I want to make this script open source because I believe their is a market that is untapped and could potentially be beneficial from this idea.

The problem I am worried about is, how can I make this system secure, so the database is not deleted by other site owners.

Thanks

You mean something like the MLS system used by Real Estate offices in the US?

or the Vebra database system used by UK estate agents?

or the kind of system used by link exchange/link farm schemes?

None of them, more of a adult picture sharing site

Oh Yeah they are REALLY in short supply!

I guess you have never been involved in the adult marketplace then.
