Joe,

Did you look at the numbers in section
at section 2.10 at the draft? Note
that the claimed comparison was made
for 3K message while using partial
notifies.

Maybe I should not have said "e.g.
XMPP" since in XMPP you can claim that
you will never use such a big presence
document due to the use of getting
other parts of the presence document
via other ways like PEP.

However, it seems to me that at the
end of a day data is data, it does not
really matter if you are going to get
it from the server of via other ways.

I'm sorry, but I just don't see how this last sentence could be true.  I
was going to write a more detailed response, but see that Dave Cridland
already did here on 10/4:

Either the work should be shown that leads to this statement, or it should
be removed.
