Isn't ivshmem in QEMU? If so, then I don't think there isn't any

Well, it means that you will inside the guest have two different
devices depending whether you're using QEMU or kvm-tool. I don't see
the point in exposing different devices to the guest just because of
NIH. Why should a guest care which device emulation framework you're
using?
It's a pretty special-purpose device that requires user configuration so
I don't consider QEMU compatibility to be mandatory. It'd be nice to
have but not something to bend over backwards for.
Well, the nice thing is that you would get the guest side for free:

You also didn't invent your own virtio protocol, no? :)
No, because virtio drivers are in Linux kernel proper. Is ivshmem in the
kernel tree
or planned to be merged at some point?
