git-annex/Command/SendKey.hs
Joey Hess b4c6da9cbd Got object sending working in direct mode.
However, I don't yet have a reliable way to deal with files being modified
while they're being transferred. I have code that detects it on the sending
side, but the receiver is still free to move the wrong content into its
annex, and record that it has the content. So that's not acceptable, and
I'll need to work on it some more.

However, at this point I can use a direct mode repository as a remote and
transfer files from and to it.
