I think everyone has lost the place on this topic. Ask yourself two
questions -
1. Why are we writing this statement?
2. Who is going to read it ?
I suggest we're writing it because we are feeling threatened by SenderID,
and I suggest that the people who read it will want it in less than 50
words.
Based on the fact that I believe we are more of a threat to SenderID than it
is to us, and readers will mostly *not* be highly technical - here's my
version:

I'll be glad to add any other links and similarly cryptic comments about the
other technologies.
Slainte,
