HACKING AND COMMUNITY
SPONSORSHIP
-Tahoe-LAFS was originally developed thanks to the sponsorship
-of Allmydata, Inc. [12], a provider of commercial backup
-services. Allmydata founded the Tahoe-LAFS project and
-contributed hardware, software, ideas, bug reports,
-suggestions, demands, and they employed several Tahoe-LAFS
-hackers and instructed them to spend part of their work time on
-this Free Software project. Also they awarded customized
-t-shirts to hackers who found security flaws in Tahoe-LAFS (see
-the Hack Tahoe-LAFS Hall Of Fame [13]). After discontinuing
-funding of Tahoe-LAFS R&D in early 2009, Allmydata, Inc. has
-continued to provide servers, co-lo space, bandwidth, and small
-personal gifts as tokens of appreciation. (Also they continue
-to provide bug reports.) Thank you to Allmydata, Inc. for their
-generous and public-spirited support.

+the Google Summer of Code 2010. Google suggested that we
+should apply for the Summer of Code program, and when we did

+around the world to hack on Tahoe-LAFS this summer. Thank you
+to Google, Inc. for their generous and public-spirited
+support.
+
+
+HACK TAHOE-LAFS!
+
+If you can find a security flaw in Tahoe-LAFS which is serious
+enough that feel compelled to warn our users and issue a fix,
+then we will award you with a customized t-shirts with your
+exploit printed on it and add you to the "Hack Tahoe-LAFS Hall
+Of Fame" [12].
