I hope not - I have over 2 million tiles stored on SD card - if file
corruption or disaster occurs, it may affect only one tile if its being
accessed at the time - imagine the effect of file system corruption on
one large archive ... you will most likely lose the lot.

Then there is the extra overhead needed - Ive gotta ask "why"? - if you
can justify the extra cpu needed for this, why not do vector maps?
