Heh... good luck.

There used to be some hacks that could mirror a telnet session at the
network level, but I haven't seen those for years. You have to either
have a telnet app that can do this or hack the network layer. Unless
you want to write a sniffer that can decode and re-play a telnet
session, which may exist, but I haven't seen.

If you just want to be able to start a session, then pick it back up
after logging out for a while, try 'screen'.

I like tcpdump with 'ethereal' for doing sniffing and decoding, but that
won't get you real-time.
