Hi Asset,


OpenLaszlo is a DHTML generation language. From what I have seen there is a plugin for rails to be able to use OpenLaszlo ( http://laszlo-plugin.rubyforge.org/) 

Rails ( as you may now ) is a web framework for ruby and it uses HTTP ( or HTTPS if you configure ) for communication with the client side ( the browser). It can be very scalable
or not  depending on how you code the app (there are no silver bullets). The protocols you commented on your initial email are more for app to app communication. 

Rails also allows PostgreSQL ( and Oracle, MySQL, ....) so that requirement is also covered. 

Regards,
Vicente
