edits. I believe they are still applicable]

I believe that approval of draft-houselye-tls-authz-extns would be the wrong 
decision, for the following reasons:
1. It would send the wrong message to both Redphone Security and other 
companies who would seek to engage in similar practice. This is not to 
suggest that any particular company did or would seek to do so, just that the 
IETF should seek to deter this behaviour.

2. The authorisation extensions have recently been implemented by a free 
software library, and problems were found in a couple of areas:

Approval of draft-housley-tls-authz-extns given current knowledge would be a 
poor decision both politically and technically.
