No apologies required!

Mostly because there's a dichotomy in Linda between tuples and tuple
spaces; tuples are not representations of tuple spaces like they are
on the Web (which is why Linda doesn't have the equivalent of PUT).
Another manifestation of this is that in the Linda protocol, only
tuple spaces are identifiable, not tuples.  The Web, through the
composite relationship between a resource/representation (tuple) and a
container resource (space), defines a more general model.

There were a lot more design flaws with Linda that explained why it
didn't become the Web, though.  But since this has little to do with
reliability, perhaps we should take it offline?
