I was thinking of a fat16 type of system I'll work of my hand scribbled
notes into an HTML document if anyone would be willing to look at it and
HOPEFULLY give me suggestions or ideas.. the main purpose of the file
system would be to have multiple files that are mainly read. there
should be very little writing.. I'm thinking about this as being used in
a web server type application.

                        maybe I should write it out in HTML anyway just to MAKE myself be
more specific :)
