[Developers] Acre hosted app licensing - BSD only?

[Tom Morris]

The MQL licensing conversation recently made me think of a couple of
other licensing issues that I've been wondering about.  The first
concerns Acre.

There are a number of references to all Acre code being BSD licensed
which make it sound like it's mandatory, not just a suggested or
default thing (and something that all Metaweb staff does), but I
haven't been able to find any place where this is actually mentioned
in a legal (or even semi-legal) agreement.  Is there a separate
license for freebaseapps.com or have the lawyers said that since the
source code gets stored in the graph and graph is CC-BY licensed that
the equivalent software license is BSD?

Similarly, there's a mention in one of the FAQs (don't have the
reference at hand at the moment) about Acre hosting being restricted
to apps which access Freebase.com as stated in the TOS, but I can't
find a ToS agreement anywhere, let alone one which says that.  As an
aside, it would be great to have all such references linked directly
to the relevant page.
