Hi Tomas, I've read it and think it is an excellent work, I'd like to see it integrated into bitcoin-core as a 'kernel module'.
I see there are a lot of proof of concepts out there, IMO every one deserve a room in the bitcoin client as a selectable feature, to make the software more flexible and less dictatorial, an user could easily select which features she wants to run.
