blocking rootkits using virtualization

Hello guys, I was going through kernelnewbies.org and came across a project "Block Rootkits using Virtualization" by riel. Basically we have to make kernel read only after boot process completes so rootkits get blocked. I have few doubts... --Is the method of making kernel read only to block rootkits used in linux kernel mainline? --have anybody implenented this project already? --what is the good way to start with above project? --any guidelines to implemnet above project?? --can I get any menor?? --any material related to above project??
