This paper: N. Busi and G. Zavattaro, “Publish/subscribe vs. shared dataspace coordination infrastructures: Is it just a matter of taste?,” in Proceedings Tenth IEEE International Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises. WET ICE 2001, 2001. ... compares Linda-like to publish-subscribe models, and finds that while Linda-like shared dataspaces can be expressed in terms of pub/sub, the reverse isn't true. Shared dataspaces need to be augmented with a special kind of global coordination operation (the authors conjecture that Linda itself may have a sufficient primitive) to be able to express pub/sub semantics. I have a hunch that there's a deep relationship to dataflow/FRP here. I'm looking into it right now, but progress is slow.
