Yes. I am actually working on adding persistant connections and
ByteString support to HTTP for this. I just wanted to get the quick
dirty and working version in there first and get some feedback.

It is quite slow at the moment, but ByteStrings should help a whole lot.

And I have other ideas I want to implement, such as intelligent handling
of redirects. (once you get a redirect, rewrite all futher urls so you
don't keep bouncing back and forth following a redirect for each file).
Also, I was looking into it changing the _darcs/prefs/defaultrepo to
reflect the redirection on '301 permanent redirect' responses (but not
temporary redirects).

This should help people migrating repository locations greatly.
