Be patient with me.  I don't see the problem, at least not yet.  I wouldn't
have brought the license to debian-legal if I thought it were beyond question,
but some discussion will be required to convince me of your assertions.

Which section of the DFSG does this violate?  It prevents me from packaging
things such that the DNSsafe library is a separate entity from BIND, clearly.
It means that someone else can't "borrow" the DNSsafe library from BIND without
negotiating a different license with RSA.  However, I fail to see how this 
restricts distribution of modified versions of BIND in any way.

This is unfriendly to the free software community at large, to the extent that
someone might want to use the DNSsafe code for some non-DNS purpose which this
license would not cover, forcing them to negotiate a different license with
RSA.  But again, I don't see how this violates the DFSG... or how it in any
way prevents distribution of BIND.

This one is the most problematic point for me.  I'd like the API to be as free
as the software, but I can't see how this violates the DFSG.  We have lots of
cases where free software implements one or the other side of a proprietary 
API, after all.
