You read the Hijack FAQ? The second entry reads as follows:

---------
Hijack is a hacked kernel written by Mark Lord that adds a host of new features to the empeg/RioCar. It includes Richard Lovejoy's VolAdj hack, IR translation so you can use third party remotes and remap buttons, a game, a built-in FTP and HTTP server, Christian Hack's v1.0 DelayTime hack (as of v201), Brian Mihulka's lighted button hack (as of v202), an easy way to attach other userland apps, and a bunch of additional features accessible through it's own menu system.
---------

I want the FAQ to explain exactly what you are wanting to know... so any advice on how to make it more "basic" is appreciated.
