Gateway Daemon Release 3
Redistribution License

Introduction and Background


GateD BACKGROUND

The GateDaemon Project at Merit at the University of Michigan ("Merit")
produces the GateD software, an implementation of several routing protocols as
a daemon to run on various versions of  Unix.  GateDaemon was originated and
developed through release 3.0 by Cornell University and its collaborators with
funding from the National Science Foundation and other sources and with
important contributions of code, testing, and documentation from a number of
organizations.  Merit provides copies of GateD upon request and at no charge
for use as specified in the copyright and other restrictions contained in the
GateD source files. 

REDISTRIBUTION OF GateD

Those who wish to redistribute GateD may do so under agreement with Merit. 
Anyone wishing to transfer GateD or any part of GateD to any third party must
first execute the GateD Redistribution License corresponding with the version
of GateD to  be redistributed. The GateD Redistribution License entails no
license fee.  Instead, licensees are required to submit to Merit for
distribution to the user community certain modifications and enhancements
which they create or are created on their behalf using GateD.   Such
distribution of licensee-developed enhancements is for the benefit of the
GateD user community and subject only to the GateD source file restrictions
and, if applicable, to the appropriate GateD Redistribution License.


The organizations who have shared in the ongoing development of GateD have
done so in part based on their confidence that others in the user community
will contribute on the same terms.  However, the  requirement to share GateD
enhancements may conflict with an organization's effort to develop products
for commercial use which may overlap GateD in function.  The attached version
of the GateD Redistribution License defines in greater detail the enhancements
or modifications which are required to be returned for the benefit of the user
community.  As well, the agreement provides for certain cases which may be
legitimately excluded from the requirement to return enhancements.  GateD
enhancements which entail third party proprietary materials, for example, are
not required to be returned.  Further, a provision has been added to allow  a
monetary contribution in lieu of return of particular enhancements.  This
provision allows GateD to be utilized in contexts which may become proprietary
to a licensee while ensuring that such use contributes to the continued
development, enhancement, support and public availability of the software.  

Please note that Merit's continued ability to make GateD available to the user
community at no charge is contingent upon the University's incurring no
additional liability from licensee's use of the software.  Accordingly, the
attached GateD Redistribution License holds Merit harmless from liability
arising from licensee's use of GateD under the agreement.  As written, the
scope of liability protection reserved by Merit is limited to only that which
would not have arisen but for a licensee's use of GateD.  In addition, the
indemnification of Merit is further qualified to exclude liability resulting
from University negligence.    

The rights conveyed to Licensees under the GateD Redistribution License are
non-transferable.  If a licensee's plans for redistribution of GateD entail
further redistribution by third parties, in collaboration with the licensee or
otherwise, such third parties should be referred to Merit so that  separate
GateD Redistribution Licenses may be executed.

Major versions of GateD are released at irregular intervals, usually more than
a year apart, when significant new functionality has been added.  Execution of
a new GateD  Redistribution License is required prior to redistribution of new
versions of GateD.
