Every time I think I have a good idea the more experiencied people tend
to show me a lot of drawbacks :-) and I just think how I can't imagine
how FB works and the lot of things that should be done to make it
consistent/confiable.

So I don't have a clue if it's easy or good to have diferent image for
memory and disk representation of the pages, or even if it's possible.

Ann and other's, for sure, will clarify your doubts.

see you !
