Well, before you discount it, did you try out your design? You could
do initial segregation of user's tables into separate schemas (say,
schema 'a' -> 'z' according to username or some better hashing
routine like brute-force round-robin assignment at user creation
time). Assignment of objects -> schema would be one additional column
in your centralized user directory table(s).
