What cost ? We have no legacy at all - we have little deployed code out
there; and just a few docs.

That is -not- what I mean (nor care too much about; as @semantics uses
the Berkely DB by and large as a backing store).

Right now

	database backend a JDBC, ODBC, ADO, whatver interface
	over which you send SQL to the backend.

	code libraries (rather than on the server).

->	A large body of SQL folks which we want to 'get' our
	language as soon as possible.

We want to instantly levarage that infrastructure and capitalize on all
those people.

In the ideal world we should be able to use the semqeb query langauge
everywhere where there is now sql over a *DBC used without having to
change the clients, their IDE's, their toolchains or their setup.

But just by just installing a Semweb query backend -and- a quick course in
the language to the developers. I.e. swap out that dinosaur SQL database;
plug in a SemWeb QL and you are ready for the future.
