No, not with Hamachi. Implementing ICMP tunneling on Windows
requires writing NDIS/IM driver or an equivalent and it is an
absolutely royal pain in the butt to support. In other words
it is somewhat hard to justify :)

Doing a bunch of traveling recently in Asia (adventures blogged here: http://blog.redswoosh.net <http://blog.redswoosh.net/>), I’ve found myself in many situations where I’ve had to purchase wireless Internet access, quite often at double or triple the prices seen in the States.

Before paying however, I am almost always able to do a DNS look-up and sometimes even ping remote hosts, though normal Internet traffic over port 80 (and various other ports) is blocked.

It got me to thinking about ICMP tunneling around these wireless “toll booths” so I could travel Asia and even the states without having to communicate over those popular ports that cost money to communicate over.

Maybe something could be coded up to tunnel over ICMP to a proxy server (or proxy peer), that then translates communication back to the intended protocol and port and forwards communication along. It seems that at least theoretically, with raw sockets and promiscuous settings, even on Windows machines, this should be possible.

Anybody have experience with tunneling over this widespread, but often forgotten protocol and port? Could it also be useful for NAT traversal in extreme conditions?
