The installation program of Delphi 2005, built using Microsoft's Installer technologies, is ready to go primetime, at least, in my opinion. With Brindha's (she's one of the integration engineers in Borland) help recently, I was able to create a script that can install Delphi 2005 silently, or with a final popup dialog giving the status of the installation.
This means that if you're an administrator or a software developer / manager assisting your systems administrator to deploy Delphi 2005 enterprise-wide, you can do so now.
The commands required to do so is placed in an article, available on the Borland Support site, in the Installation and Registration category of the Delphi product area.
