Oh yes, it works, I've tested it.

I was speaking about Event/Trigger in the RDBMS itself.

In a RDBMS, you can define some specific SQL code to be executed when a
row is inserted/deleted/updated.

So, the KIOSlave have just to update a row (the modified KWord doc).
And the RDBMS will automagically execute some SQL tasks you've defined
when a such event (an RDBMS-update event) occures : storing the old
version of the kword_doc, increment version number, and storing  the new
version of the doc in a new row.

That's very easy, about 10 lines of SQL, and may be very usefull.
