I'm probably missing something obvious here... but why? What kind of
dynamic content do you need?
Or do you mean vital in the sense of "prove it works"?

Very true. And unrestricted CGI is a Bad Idea on a production server
with multiple projects. All it takes is one project with one mistake
in one CGI script, and Common-lisp.net grinds to halt because the disk
gets written full, or all the time is spent swapping, or an attacker
uses the CGI to snoop the system, etc.
On a single project website this is not that much of a problem:
people can hurt themselves, but not others.
Like Mario pointed out, this is why chrooting is *vital*. It's not
about trust, but about security and robustness. And I'd add "running
as nobody" and "cmhod -R o-w" to the list. ;)

Very true. But then I don't think we should be offering PHP either, ;)

I'm not worried about anything as long as the number of hits is
moderate. What I am worried about is what will happen when the number
of hits increases. (Getting slahdotted being the worst-case scenario.)
This is why I think only projects that actually need dynamic content
on their pages should have the means for it. I'm not too interested in
starting to differentiate between varieties of "need", as long as a
clear case can be stated.
