Any read-only operation ;-)?

On the object-transfer front, that would mean fetching from,
archive-r from, and perhaps creating bundle from.

Locally, log, grep, blame, gitk (but only the browsing part), etc.

If a read-write borrower borrows from a read-only location via the
objects/info/alternates mechanism, anying operation to the borrower
should also work without modifying the borrowee.
