libqemu.so would be a C API.  C is not the first choice for writing GUIs or management applications.  So it would need to be further wrapped.

We also need to allow qemu to control the display directly, without going through vnc.
For the current functionality I tend to disagree. All that we need is an shm vnc extension that allows the GUI and qemu to not send image data over the wire, but only the dirtyness information.

It still means an extra copy. I don't think we want to share the guest framebuffer (it includes offscreen bitmaps), so we'll need to copy it somewhere else. It's even worse with qxl/spice where there is no framebuffer.

As soon as we get to 3D things might start to look different.

Very different.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
