[tahoe-dev] RSA slides: submitted

[Brian Warner]

I just submitted the slides. I expect that the reviewers will come back
with some issues, and that we'll improve some things in the meantime.
I've attached the submitted version (PDF, not ppt) here.

I wasn't able to find a clean way to remove "storage index".. the
progression of pseudocode examples was just too hard without it. I also
wasn't able to draw up the pictures that I wanted of our mutable and
immutable file formats, although they'd probably have added complexity
to an already-dense talk.
