Anthony, thanks for looking into this / cooking up a patchset for this.
Unfortunately I don't have the time to look into right now. Likely I won't
have any time for this until after kvm forum. But if no-one has given this
a serious look by then I'll try to convert the various spice related
chardev frontends / backends to this and run some tests.
