Years ago, long before GNU social or StatusNet or #ActivityStreams, I remember actually working on something similar (more like a #MUD...) with reified actions that distributed over the network; it was my intention w/ _that_ (though I never actually got there) to be able to publish #REVISION actions and also have them propagate in the same way as less meta actions.
