Oh, and it's probably worthwhile pondering what the viruses will do if this mechanism comes into widespread use.

While I was looking for the reference above this also came up:

when bat cells quickly release interferon upon infection, other cells quickly wall themselves off. This drives viruses to faster reproduction

Quite a way from whole-animal physiology in the referenced research, by all means, but it's a fair point, right.
