[gentoo-dev] Web Hosting solutions?

[Gregg]

I am looking to run a small web hosting box.  This is more for me to learn
the tricks of the trade than anything else.  I know the basic sets of
tools I need and that they are already in portage.  What other tools in
portage besides these are there.  I could spend hours searching the web,
finding something, seeing if their is an ebuild already, ect... But I
figured I could get away with just asking here, I think it is a relavent
question to see where gentoo is on this matter.

Apache, php, ssl, perl, mysql, mysqltool/phpmyadmin, and pick your mail
server.  They are already all in there.  Now what about a client
management/billing system (web based), some form of control panel for the
customer to log into and edit things.  What packages exist that fill these
needs (and any needs I might be missing) already in gentoo's package tree?
