[GRAAP-WG] Modification to the wiki Page on Renegotiating an established Agreement

[Omer F. Rana]

Hi Michael,

Yes, I off course agree with your statement that all three must be taken 
into consideration. In practice, many
implementations do not follow this line however -- but they should.

I guess there is a trade off between making the protocol too complex -- 
so much so that no one will actually
use it -- vs. making it complete -- so that it takes account of 
everything that is useful. But you are right.

Thanks also for the additional links. Seems like I have my reading set 
out for this w/end.

regards
Omer
