Thanks for doing this.  While there are some typos in there, it generally covers the differences accurately.

One comment on the basic differences on page 1:

The Cloud Model intentionally avoids any indication that the Cloud Service can change or configure the Local service in any way; it can only submit Jobs and monitor status.  It appears that IPP-SIX also provides for management of the local Service by the "infrastructure printer".

IPPSIX doesn't support remote management of local services.  It would be more accurate to say that it allows for remote monitoring/accounting of individual Output Devices (Imaging Systems in SM parlance), while the current Cloud Imaging Model only allows for monitoring/accounting of the combination/collection of Output Devices/Imaging Systems associated with the Cloud Imaging Service.

Thus, with IPPSIX you can answer the question "How many pages did I print to the laser printer at 320 Sycamore?", but the Cloud Model cannot because the existence of local Imaging Systems/Services is (currently) hidden, as are the details of how a Proxy tells the Cloud Imaging System/Services which Imaging System it is representing at any given time.  I don't know whether we want to expose those details in the Cloud Imaging Model, as those details may depend on the binding/implementation - perhaps we may want to include some discussion about which binding/implementation details are not specified in the model that need to be?
