RE: [tcpm] tcpsecure & IPR

Mitesh,

Thanks for your answer. However, I don't think that presentation 
addresses my concerns.

There's one basic concern that I have:
Let's say I want to encourage vendors to implement tcpsecure. Vendors 
will want to be assured that they want have to pay anything, or be 
sued, or whatever. However, I have not been able to find an 
"official" statement by Cisco regarding this whole issue.

Scott may be extremely accurate and right in what he says. But, as he 
acknowledges in his presentation, he is not speaking for Cisco.

A vendor willing to implement tcpsecure will want to read a statement 
from Cisco claiming whether vendors implementing tcpsecure will have 
to pay a royalty, or whatever.

In the event that somebody implemented tcpsecure, and then Cisco sued 
them for that, I don't think vendors will be able to defend 
themselves by claiming "Scott said that we wouldn't have to pay anything".

The presentation does not say whether the pending patent is on all 
the countermeasures, or only on some of them, either.

Kindest regards,
Fernando Gont
