Not sure if the Mahout project can qualify, but the US National Science
Foundation (NSF) is asking for proposals to use a massive Hadoop-equipped
cluster - from
<http://technews2u.com/2008/02/25/supporting-cluster-computing-in-the-research-community>:
In October of 2007, Google and IBM announced the first
pilot phase of the ACCI, which granted several prominent
U.S. universities access to a cluster of thousands of
processors running Apache’s Hadoop, an open source
distributed computing platform inspired by Google’s file
system and MapReduce programming model.

Starting this year, the NSF will work to evaluate
project proposals from academic researchers across many
disciplines and select some of the most interesting and
promising projects to receive ACCI computational grants.
More details, including information on how to apply for
access to these resources via the NSF’s Cluster
Exploratory (CluE) program, will be posted soon on the
NSF site.
