<h3>Kevan Carstensen</h3>
<p>Kevan is slowly but surely building the pieces that Tahoe-LAFS needs to
interact with a new type of mutable file, called MDMF.</p>
<p>Unlike current mutable files, which are processed all at once, MDMF
mutable files are processed in small segments, very much like immutable
files. This has a pronounced effect on memory consumption, especially for
larger files -- peak memory consumption will no longer be proportional to
the size of the source file, but will instead be proportional to the size
of one segment. This will effectively enable the use of large mutable
files.</p>
<p>Currently, Kevan has defined the storage format for MDMF mutable files,
written writers and readers for that format, written an uploader and a
downloader that can process files in segments, and altered a lot of
mutable file code to deal with segmented files. He is in the process of
altering the webapi and other frontends to take advantage of segmented
mutable files. He hopes to have a usable beta of some MDMF functionality
available by July 16th, 2010. You can follow his progress on <a href='http
://tahoe-lafs.org/trac/tahoe-lafs/ticket/393'>ticket 393</a>.</p>

I have a number of painful analogies that might make for good non-
technical explanations about what MDMF does, and why it is better than
SDMF -- if you think they would be useful, just let me know and I can work
them in. :-)
