Yes, that makes sense. More difficult for products like mxODBCZopeDA to
check licence use but heyho!

In general, yes. In practice, in testing this wasn't possible and maybe not
a bad thing to have done this: threw up a problem with possible iODBC and
We still think that in such an environment it might still make sense to

for discussion on this and a possible ZSQL replacement together with other
issues at EuroPython in two weeks.
