Right, the filtering for beacons is already in place in vcl and responses are sent right away so as far as I know there is no better place than varnish for this code. See example:

Do you see any fundamental problem with this?

 A dummy image request seems rather reasonable. (I assume varnish can handle such load of "atypical" requests.)
Making additional requests is ugly, but until we get SPDY our articles typically make dozens or hundreds requests, so the effect looks negligible.
