My intended users would range from "power users" who run their own webservers to users with more limited skills who would know enough to find a script on freshmeat and follow basic instructions about editing the config file with a text editor. Comparable to the level of skill of a typical user who was going to install their own blogging software on their webserver account (rather than use something like blogger.com). As I mentioned above, I'd like to have a "systemwide" installation option along with the per-user installation.
