Comment (by cypherpunks):

 To do non kludge solution, pt of future need to implement something like
 Padding Negotiation (see proposal 224 for tor). Most vuln timings for
 observations are tls handshake, tor link handshake, one-hop circ handshake
 (maybe). TLS handshake is enough for kz, but that doesn't means it
 measures only that. (and yes dpi vendor have nothing about tls/tor
 handshakes, they just measured tor browser out of box)
