I haven't used JavaSpaces specifically, but I did put together a
prototype using the Objectspace Voyager product back in '97 (IIRC).
Voyager consisted of several frameworks supporting different styles of
distributed computing, and one of those was a tuple space based
framework very similar to JavaSpaces. I forget the name of that
framework though.

It was very easy to use, and once built, very easy to add new spaces
into the mix... which is unsurprising given that all spaces exposed
the same interface, meaning clients could interact with every new
space that was created without requiring upgrades.

It was also instrumental in helping me to fully appreciate the scope
and power of the Web, as it shares many important similarities with
tuple space based systems. The Semantic Web even more so, in fact.
