Anyone with a bit of a deeper network and cryptography knowledge care to comment on this technical proposal:

Basic idea seems to be to decouple proof of work blocks from transactions blocks (while keeping the two connected, obviously), without the usual trade off that means more tx -> bigger blocks.

Looks plausible to me, and actually a lot less "radical" than, say, turning Bitcoin into a proof-of-stake system. That said, I don't have sufficient technical knowledge to judge if it only appears plausible at a glance or if there's a catch I don't see right now.
