Anybody care to briefly describe the merits of a two-tier architecture vs a three-tier architecture when using OpenBD? I expect a base OpenBD install places the app server on the same machine as the web server for the sake of convenience. But, if I'm planning on scaling with OpenBD (and Google App Engine is not an option), is it a best practice with OpenBD to segregate the functions onto different machines?
