Dead Souls is similar to Lost Souls. It's a LP mud, meaning they share a common ancestry. The important thing about LPs for you at the moment is that the codebase is in two parts, the driver/engine, and the lib. You write most or all of the mud in the lib using LPC. Normally you don't have to do much with the engine, which is written in another language (for LS and DS I believe C).

So to answer your question, Dead Souls is like a starter kit for making your own mud. You certainly can make a RPI with it. If you have more specific questions I recommend you hit up the forums at lpmuds.net.

Now there are other codebases you might be interested in. There are some barebones codebases such as NakedMUD that could work. There's the RPI engine too,
