Another shot of the rainscreen
This stuff rolls out over the felt paper on the whole house, with the drainage channels (see them here) going vertically. This creates an airspace and drainage plane behind the siding and on top of the felt paper, so that any wind driven rain that gets behind the siding can roll down and out. It also allows for air circulation behind the siding - we're hoping that that will help the studs to dry out over time (since, thanks to the miserable weather, it looks like they will not get to fully dry before we close up the walls).
Rainscreens aren't typically used under Hardie around here, but given the combination of fierce wind-driven rain up here on the hilltop and the fact that we are closing up the walls when some of the studs still have a relatively high moisture content, we've decided a rainscreen is worth the extra cost and effort.
