It's always interesting to demonstrate that an attacker can study your browsing habits and use that knowledge to exploit a computer/steal passwords (dns poisoning/phising/etc...).
I certainly agree with you but you'll find urlsnarf informations in sslstrip's logs... So it doesn't bring anything new, imo.

Xplico is an interesting (and powerful) tool. It's best run on a dump (live capture mode is not as useful). It's easiest used through its web GUI so I agree wouldn't integrate well with yamas - just mentioned it while we were discussing image extraction.
All right, thanks, I thought you mentionned it for yamas, not as general knwoledge. But it makes more sense this way and it sure seems to be a nice tool ! I'll try to have a go at it when I figured how to launch it
