You can write your own overlay, that sets appropriate handlers for write 
operations (add/delete/modify/modrdn and some extended operations). 
Overlays are supported by recent 2.2 and HEAD software.  Or write a 
slapi that does the same.  SLAPI is supported by late 2.2. and HEAD as 
well.  A very rough solution for older releases is to proxy the real 
database behind a back-perl (preferred) or back-shell (deprecated 
because non thread-safe) that deals with write operations and leaves 
read operations untouched.  This is going to yield poor performances, 
but should work fine for "fast" prototyping.  The suggestions are in 
order of (decreasing) preference for me; others may see it differently.
