Awards for orgs which contributed to open source

It's great when organizations which use open source software give back 
by contributing time to an existing project. The Mellon Foundation 
has awards for organizations which do this. I'm on the committee at 
the moment.
Can you think of or do you work for maybe a non-profit organization, 
including school or university, which has contributed back to an open 
source project?
If so, please nominate them -- could be your own university -- at http://matc.mellon.org/nominate
Deadline: April 14
Thanks in advance
Tim
The deadline for nominations for the 2008 Mellon Awards for Technology 
Collaboration (MATC Awards) is April 14, 2008. The MATC Awards consist 
of up to ten 50,000ドル or 100,000ドル prizes, which a receiving institution 
can use in a variety of ways to continue its technology leadership. 
The awards honor not-for-profit institutions that have demonstrated 
exemplary leadership in the development of open source software for 
one or more of the constituencies served by The Andrew W. Mellon 
Foundation: the arts and humanities in higher education; research 
libraries, museums; performing arts organizations; and conservation 
biology.
