transparent RDBMS layer?

I'm considering writing a transparent RDBMS layer for Lucene using 
triggers from the RDBMS (or maybe just patch something like HSQLDB).  

Something like this:

CREATE TABLE myTable
(
    PK          int,
    sometext    VARCHAR(3000)    luceneindex,
    someFK      int
);


Did anyone else consider this?

Off topic, or just not interesting?

I did how ever created such functionallity using HSQLDB-triggers. 

The code is a bit ugly and should rather be represented in a late
bounded controller class called from (as in present code) multiple
triggers in HSQLDB to save the JVM from threads and synchronized
calls to Lucene.
