Wow!  Check out these great slides from Aaron Cordova's talk about HadoopWorld!

They clearly explain why you might want to use Tahoe-LAFS instead of
HDFS to store the data that you are computing over with MapReduce.

They also include some performance comparisons between Tahoe-LAFS and
HDFS under MapReduce.  Aaron: if you're reading this, could you give
us more information about how Tahoe-LAFS gets used by MapReduce?  The
write performance was terrible.
