Whaou !
So we are not so far from real-time after all, taking my exemple :
if ~0.5s is acceptable for a full screen user view and experience
so in a multi-thread environnent, it means that we "just" need one CPU-core by 
tile to render. (well, at list, for one user ;-( )
But octo-core CPU are on their way...

Very clever too ! Using the diffs !!

I just can't understand the advantage into putting code in a apache module, 
instead of "just" doing some rewrite to a python/cgi wrapper that would 
generate the tiles...
Well, after all, why not, for a few % boost ?
