I _may_ become the newest member of the SOFA board very soon... I was
in contact with one of the current members as well as the Chair over the
past week and mentioned several times problems with the license.
If I do become a member, fixing the license (probably requesting that
they simply make it BSD or maybe LGPL?) will be one of the first things
that I pound on.
I really like the idea of astropy using SOFA under the hood if at all
