Hey, calm down a bit. I can't see any use for Nautilus on an e-smith box, which 99% of the time is only accessed remotely, but I also don't think the FM directly addresses the question, either. This isn't the dev forum; this is the "experienced user" forum, which _is_ the proper place for questions like this (as it would be a customization of the e-smith server).
To answer AJ's question, it'd be pretty involved, as you'd need to install all the X11 and GNOME RPMs from RedHat 7. This wouldn't necessarily be difficult, but it could be time-consuming, and I don't see the point of putting a pretty local GUI on a server (a good remote GUI is another question, but the e-smith manager is pretty decent).
