i've ever invested some time to try that out (Bart PE -
http://www....nu/), take a look at this site, there's lots of information and links to orther site sharing so called "plug in", like office plugin, 7-zip plugin, nero burn plugin, etc....
the best you can do is "TRY IT YOURSELF", you'll never understand what's going on before u really try it...
i recommend using a CDRW disk to try, you'll be wasting some disks if you use CDR.....and try to create plugin youself to learn more, i had created like "CDBurner XP Pro" plug to replace nero....
it's not difficult to build one but is difficult to fine tune it...
