It all gets a bit more interesting when you factor in that a lot of
spam is sent from forged (but real) email addresses, via the magic
that is open relaying. Can you prove you *didn't* send a piece of
forged email ? :-)
The FreeS/WAN folk have been working on what they call opportunistic
encryption, which could be an interesting way of frustrating traffic
gathering activities...

It's a bit convoluted, though - e.g. I wonder how many people on the
list are in a position to add IPSEC keys to their DNS records ?
Be aware that running a VPN (like IPSEC stuff) may already contravene
your conditions of service (that's before it's made illegal ;-) ...
http://www.ntlworld.com/legals/user-policy.htm:
18. Use of Virtual Private Network (VPN)
As stated above, the ntl Internet and/or Interactive Services are for
residential use only and we do not support the use of VPN. If we find
you are using VPN via the ntl IP network we may instruct you to stop
using it and you must comply with this request. This is in order to
prevent problems to ntl (eg network performance) and other Internet
users.
Got to watch our for those VPN performance problems! Oh yes :-)
Cheers,
Martin
