A RewriteRule directive won't actually match the hostname at all; it only
operates on the URI, so the domain part of the match has to be moved up into
a RewriteCond above and capture into %1,%2 instead of $1,$2.

That would turn Joe's rule into something like:

RewriteCond %{HTTP_HOST} ^([a-zA-Z0-9\.]+)-([a-zA-Z0-9\.\-]*)ezproxy\.switchinc.\org$
RewriteRule (.*) http://%1.%2ezproxy.switchnic.org/$3 [N]

Likewise, untested. The hyphen replace is problematic for mod_rewrite.
