Yikes, that's surprisingly close to my dissertation topic, although
missing a few crucial details... :-) A brief abstract is posted here,
if interested:

Regarding the differences that Michael Champion noted above between
tuplespaces and the web:
a) Yes, of course, however it should be noted that one is simply a
degenerate form of the other, in which URL is the only field matched
against.
b) There is no reason why tuples cannot contain hyperlinks to other
tuples, by GUID or otherwise, within their structure. Indeed, this is a
commonly implemented pattern within tuplespace systems.
c) Agreed, however there has been progress on that front, most recently
the DASL draft prepared by the WebDAV WG, which introduces an extensible
method, SEARCH, to the HTTP protocol stack. Although not defined
explicitly in this draft, the query grammar used with SEARCH could be,
for example, XQuery or similar -- allowing server-side searches of XML
resources within the provenance of the search arbiter.
