The summary says the modifications should be sent to the Initial
Developer (which isn't free), however nothing in the license itself says
that. I think a statement acknowledging that this summary isn't binding
would be a good thing to obtain.

No right to sell. I think this isn't good.

The indemnification clause looks scary. However it is only here to
"retaliate" against false claims, so this is reasonable. I don't know
about corner cases, though.
