Hello Jakub,

not only are we interested: we have been talking about it for a while,
but lack of time has not allowed us to pursue it.
So yes, it would be very useful. As far as scope it seems like you
already have a good grasp of what to tackle, and we are more than happy
to answer any questions you might have.
I would like both Bela Ban and Richard Achmatowicz to add their thoughts
to this, as they have more intimate knowledge with the tools and the
concepts behind formal verification.
