Yup. That's what I'm thinking about right now.
One of possible decisions is to move stacking into the kernel and have
an optional usermode part 'stacked' through a 2 'stub' drivers.

I guess, demux can be done by 'top' driver or by drivers layout. There
are several ways, that have little impact on the total design.
