Okay so the only hold up on this is OS X. Anyone have a machine they can test with?

Confirmed that it is an error on OSX.

  1) Remote can download from a remote:
     Error: No transport bound to this remote

Ruh Roh.
Looking at the diffs in libgit, the error has been updated in 0.22.x to "This remote has never connected". So a transport is not guaranteed to be set by libgit until you've already done a fetch, which sort of defeats the purpose. It's just odd that it works in win/nix.

I'm digging a bit deeper now, but we may have to play some games in the C++, but we're gonna have to work in there soon for the iterator stuff, so maybe it's time. Perhaps some sort of generating functions both sync and async with a fallback, or something.
