It is certainly impressive & clever but first two critical questions.. Is there a committment to long term (many years) development & maintenance of this, or is it just a short term experiment which will have attention dwindle in a year's time ? Is there a compelling real world use case for this that will justify carrying it in QEMU, or is it a case of "it exists because it can" ?
