There is a public JGit SSH based daemon running at review.source.android.com, on port 29418. But no public git-daemon that I know of.

You can easily set up a JGit daemon yourself, assuming you have a 'javac' available:

  git clone git://repo.or.cz/egit.git jgit
  cd jgit
  ./make_jgit.sh
  ./jgit daemon --export-all . &
  git ls-remote git://localhost/.git

JGit does it fine.  I retested locally with this:

 perl -e '$s="git-upload-pack $ARGV[0]\0hosterver.com\0user=me\0";
   printf "%4.4x%s",4+length $s,$s
   ' /.git | nc localhost 9418

But yea, repo.or.cz hung. I see the bug in git daemon, I'll post a patch in a second. Don't do that test anymore, anywhere.
