Relationship between supergranulation flows, magnetic cancellation and network flares

Solar magnetism gets concentrated in the chromospheric network. This results in a roughly hexagonal pattern formed by surface flows that follow the convective supergranulation structure. The intense field strengths at the edges and vertices of these cells can support "network flares" that can occur far from sunspot groups, noting of course that the "active network" may concentrate the relict sunspot field that appears to diffuse away from active regions on solar-cycle time scales. See also the Fisk cartoon describing what might happen in the "magnetic carpet". We would really like to know if similar physics explains both network flares and common, or garden-variety, powerful flares in active regions. This paper is heartening here because it mentions shearing and hence perhaps coronal current systems, though presumably on a network scale and not so concentrated.
