I apologize for my slow reply to the very sensible comments below. These all
make sense to me, and I have discussed them with the other key members of
the Panda3D team at Disney, and there is general agreement that these seem
like reasonable suggestions (at least to the software developers).
Unfortunately, the lawyer who originally helped draft the license has left
the company, and it is taking some time to get a new Disney lawyer to adopt
this project. As soon as we can get a lawyer to help us either change the
license appropriately, or explain of why Disney would prefer not to, we will
I appreciate your patience in this matter, and the detailed feedback the
members of this list have provided.

Clause 1 appears to be your mutual assent clause. Good. I would suggest,
however, that the last sentence couple sentences be clearly written in the
conjunctive or disjunctive (I suspect the drafter meant to use the
Clause 6 (the treaded anti-advertising clause) is understandable, but is it
really needed? If there is no implied or explicit right to use a Disney
trademark or service mark anyway, why is the clause necessary? The
anti-advertising clauses have been a source of discontent with free software
folks, but I do not think the OSD strictly applies.
(Minor point here) Clause 7 is informative, but it says nothing about the
relations between licensor and licensee; hence, I am not sure it warrants
the prominence of an entire clause of the body of the license.
Clause 8 is unclear after the first sentence, which is probably all that is
I feel obligated to mention that using approved OSI licenses as useful
templates in drafting makes good sense, but as touchstones does not.
