It was definitely at least partially tongue-in-cheek ^_^
I bet you could figure out the physical aspects. E-ink tech itself has come a long way in the last few years following some patent expirations, and the electronics stuff is basically just a yubikey JB welded to a license plate frame. The cost per unit would be pretty low at scale, so just replacing borked units seems pretty doable.
Imo, a bigger problem is competent implementation. Yeah sure, the DOL is gonna run a bunch of PKI infrastructure and not mess that up. At least in my region, just keeping a largely static website up seems to be a struggle.
