It's the one you're going to have to write, or coerce somebody to write, if you want it that much.

I have a sneaking suspicion that SpamAssassin's core could probably be pressed into action here, wrapped in a HTTP proxy. It wouldn't scale terribly well, but it might be enough to keep tabs on a few tens of hosts that you expect trouble to come from.

HTTPS would be a bit more tricky and would require the co-operation of the cybercafe to install your CA cert on their browsers and crank down the security settings so you could do a MITM attack.
