A more recent version, which appeared at ACSAC in December 2007 can be
found at:
http://www1.cs.columbia.edu/~angelos/Papers/2007/SSARES_ACSAC.pdf
Since then, the student primarily working on this(*) has improved
performance to the point of being able to search a couple of email
messages per minute or so, with further scope for improvement. The
very large storage overhead remains, but can probably be reduced by
half or so.
(*) Adam Aviv; he was an undergrad at Columbia, now pursuing his Phd
with Matt Blaze at UPenn...
