Philosophy of DMZ

["Barros, Jacob" <jkbarros () GRACE EDU>]

I've run into a situation where a solution we are implementing requires
a web server to be on our inside network but needs to be accessed
externally.  This is happening much more frequently than I would like.
We're doing some long-term planning and my office would like some
feedback from other institutions.  

If I'm going to have to keep adding servers that can be accessed
directly, is there still reason to have a DMZ? My understanding of
having a DMZ, is to not allow public external access to internal servers
and all requests to internal servers should be answered by a
proxy/reverse proxy server.  Am I just an idealist?  

Can anyone share experiences with proxying?  Anyone ever scrap their
DMZ?  Any policies that you can share on external access to internal web
servers?
