[CNG] I think this is probably a good idea. I thought this was a way to 
minimize duplication rather than being related to distinguishing between 
the owner and who is viewed.

[CNG] I'm not sure we need to re-define view. I think we just need to be 
more specific on the scope of the existing participant attributes.

[CNG] We could do this. I'm not sure its strictly needed however I'm not 
against it. I'd like to hear other opinions.
