Thanks, David. Noodling on any impact of the respective entities 
involved may be a future consideration.  I think these comments (yours, 
mine and Ashok's) start to provide some indications of the importance of 
context here.

It may be important now and more so in the future, not only the role 
(client, server, other) but other aspects that could be typed (i.e. 
obligation). Thanks.
