This is really awesome.  I'd suggest everyone to click the first link
below and read the README.md file (conveniently rendered in HTML at
the bottom of the page).  A couple questions:

1) What is the UI?  Is this a command-line tool or is there a GUI?  (I
actually hope it's just a command-line tool; I like the idea of
separating file transport from searching and viewing/playback.)

2) This seems a great storage and transport system.  But why does it
also do encryption?  Don't get me wrong -- encryption is great.  But
why insist that it be used for all content -- why not allow me to just
publish an unencrypted file (or a file encrypted with a different
algorithm)?  From a layering perspective, given that this isn't
designed to be used on its own (eg, I need some "out of band" method
to know the SHA1 of the content I want), why not just push encryption
up a layer?

Thanks!
