[CentOS] chroot a few apps

Hi.

What kind of chroot should I use, if I want to make a more secured
desktop, running e.g.:

pdf reader
webbrowser
audio player
video player
openoffice
picture viewer
mua
ooo
virtualbox

e.g.: if theres a javascript vulnerability in google chrome [I haven't
heard a NoScript extension for it :( ] a chroot would be good for
stopping it from doing something bad with the whole system.

or e.g.: I have to open a .doc file, that I don't trust, or a PDF can
contain malicious code :(

Any tips/docs/howtos?

Thank you!
