Unless you get a blanket license for a particular algorithm. As far as I know,
this is NOT the case for CDMF.

Apart from this, I don't want to be involved with discussing the
appropriateness of CDMF, as this is a project of a different IBM group. (of
course I can
connect interested parties to that group.)

That's different - Uri talks about `blanket license' which does not look at
the application. But CDMF does NOT have that as far as I know.

Completely agree!! I'll join Ran.
