Yes, it's quite doable in user space(qemu) with a kernel-enhancement.
And it would be easy to convert a separated daemon process into a thread

One more question.
Does your architecture/implementation (in theory) allow KVM memory
features like swap, KSM, THP?

By adding some module aliases, programs (or users) won't have to explicitly
call modprobe. Vhost-net will always be available if built into the kernel.

When someone comments in a bug in kernel.org's bugzilla, the bug reporter or
the CC list can't receive an update email for that.
For example, Gleb and Avi updated the following bug, but I (the reporter)

Hi All,
This is KVM upstream test result against kvm.git
188fc33198ddb1469562d40de33bcc29e7e2ed5f based on kernel 3.2.0, and
qemu-kvm.git 9501d0f1b6efc83f69d06b27a625bad71d30d58b.
We found 2 new bugs and no bug got fixed during the past two weeks.
New issues (2):
