I'm quite addicted to Lost, and came across this link on MeFi today, postulating the numbers in the show are linked to a book called "Genetic Mirror Theory and other Natuarlly Occuring Phenomenon," by Marsille Roussau.
Of course, seeing as how this book and author don't seem to actually exist, the possibility remains that this is just another fun goosechase by the Lost creators.
Fun note--- in the last of these links, embedded in the code of the web page are the messages:
If anyone should find this message, please get word I'm alive and stranded on an island somewhere in the South Pacific. Please send help soon. Things are bad. And they're getting worse...
Sally
and...
I survived a horrific plane crash and am stranded on an island somewhere Northeast of Australia and Southwest of Hawaii. In the event that I am never found, please forward word of my fate to my parents.
