Tunnelling SQL over HTTP with MDB2

Hi, As you all know many hosting providers only permit access through the database server from the web server, not from the outside. I'm currently on a professional project where such remote database access is needed. There is a simple solution : encapsulating SQL queries into HTTP requests. There's a project out there named "PHP Tunnel" that does that : http://www.mysqlfront.de/manual/fphptunnel.html But wouldn't it be great if that was handled as part of the abstraction that MDB2 offers ? One would call $mdb2->query() as usual and that could run on a local or remote-over-http server.... This would simply require to write a new MDB2 driver, and a little server-side script to perform the real database queries. The only critical part I see is at the authentication/security level. Or have I missed something ? Is this already possible ? What about DB ? Greetings, -- Olivier Guilyardi
