Oh, sure it is possible (except for remote snapshot):
$ /usr/bin/git fetch git://localhost/foobar
fatal: remote error: R access for foobar DENIED to anonymous
$ /usr/bin/git push git://localhost/foobar
fatal: remote error: W access for foobar DENIED to anonymous
$ /usr/bin/git archive --remote=git://localhost/foobar HEAD
fatal: git archive: protocol error
$ /usr/bin/git --version
git version 1.7.6.3
Supported for fetch and push since 1.6.1-rc1 (And 1.6.1 was over
2.5 years ago). Oh, and even before that, but with slightly more
ugly error message.
Oh, and adding interpretation of ERR packets to git archive is easy
(and I even happen to have git:// server that can send those to
test against):
$ git archive --remote=git://localhost/foobar HEAD
fatal: remote error: R access for foobar DENIED to anonymous
(I also tested that remote snapshotting of repository that should be
readable succeeds, it does).

Subject: [PATCH] Support ERR in remote archive like in fetch/push
Make ERR as first packet of remote snapshot reply work like it does in
fetch/push. Lets servers decline remote snapshot with message the same
way as declining fetch/push with a message.
