Getting past the memory and bandwidth issues on the servers is technologically possible but we are talking one to two orders of magnitude more expensive equipment wise. So unless we want to boost our subscription costs by a lot, we will have to wait for technology to catch up to our glamor dreams. I believe they are due for new servers sometime around 6.x but that is only speculation. Maybe we will see some new options around then. I believe Yoshi was dreaming about updating the graphics engine in the neighborhood of 7.x.
