In addition, when using spice for local usage, you also have the overhead of redundant rendering on both server side (when required), and client side. We also need to consider rendering everything on the server side.

Yes, and when we decide to render everything on the server side, then having shared memory becomes really
useful...  :)

We can then send the settings to the server upon connection. As a second stage, I would continue with an automatic detection, something like hans suggested.
