Stefan,

Gerardo Richarte and I have implemented something for packet capturing 
and injecting in Squeak. We wrote an article in the August SqueakNews 
issue: Story of a Quake Packet. You can download it for free from 
http://squeaknews.com.
I've implemented lots of things with this, including a TCP/IP stack, 
fingerprinting tools, port scanners. The most recent version of the 
Packets stuff is at 
http://community.corest.com/~luciano/tcpip/packets.tar.gz.

What else are you working on?

Cheers,
Luciano.-
