A "web server" and a "web service" are two different things. Usually, you can set up \
a web server to serve your service. But often your service depends on a specific type \
of server. For example, if you want to just serve a fastcgi instance for a RoR \
service, you'll need to install software that allows you to do both Rails \
applications and fast cgi.

RPC usually stands for "Remote Procedure Call." There are a lot ways to do that - \
using port 80 and a web server is just one way. It helps if you specify EXACTLY what \
you want to do. Like, I want to execute a database command or I want to squirellize \
the cat tray.

Sounds like you want to use yum or some form of yum automation. But I will tell you \
right now, I wouldn't let you do this on my machine. You will need the root password \
to install and application on a client machine, and you are unlikely to ever get that \
from a security conscious user.

You are going to have to be much more specific. And you most likely are going to have \
to do some of the coding yourself. It sounds like you want to do some kind of remote \
archiving. But this sort of thing, i.e. client / server programming, is non-trivial, \
though there are tons of working tools available and Linux is very good at this sort \
of thing.
