yes. However, from what I see in the code it looks like unix socket works
if VE does listen() and VE0 does connect() only.

unix socket is done so by design and won't be broken 100% as there are some
tools using this property.

for fifo - not that sure and didn't try that. however, if it works (it should!),
most likely won't be broken as well.

Thanks,
