Looking at the http://httpd.apache.org/docs/misc/rewriteguide.html , it 
seems you can use perl scripts to control mod_rewrite behavior. This 
should give interesting opportunities for this kind of file checking stuff.

A FAQ: How can we solve the FOO/BAR/QUUX/etc. problem? There seems no 
solution by the use of mod_rewrite...
Solution:
Use an external rewrite map, i.e. a program which acts like a rewrite 
map. It is run once on startup of Apache receives the requested URLs on 
STDIN and has to put the resulting (usually rewritten) URL on STDOUT 
(same order!).
