I agree so much that .. i cant hold it anymore :-)
Although not quite ready for primetime I'd like to say a few things 
about the effort we've been cohordinating for the past 14 months now.
"DBin" [1]  is basically, as you mention, an  .. "integrated semantic 
web program".

Basically all the main aspects are (or are to be) considered at the same 
time, in the same effort to show the benefit "of it all". Thus the logo: 
a guy has climbed up the "semantic web tower" (abeit a "small instance" 
of it) and is taking a look at what's interesting (hopefully something).

We started the works by designing and implementing a semantic web P2P 
algorithm (RDFGrowth)  that could at least theoretically scale "in the 
wild". We obtain this by making a large use of local resources and not 
(almost ever) bothering others in the network with your personal 
queries. (no distributed queries allowed) [2][3] .

We continue with a new trust infrastructure capable of signign RDF 
subgraphs thus maintainin a track of who said what in the same  model  
and allowing precise filtering of the data you have. Such struicture 
(called RDFTrust) contains an API which can be easily used in any 
existing semantic web project (since the signign and provenence is 
completely based on standard reifications)

We continue with a new visualization made with lightweight "scripted" 
applications for the domain of interest say "the world of beers" as in 
the demo. We call these "Brainlets".Please take a look at the 
screenshot., what you're seein is a collaborative environment where 
people discuss, add contributions, structured information, unstructured 
data (but well inserted in the structured mesh)

Anyone (witha  bit of ontological knowledge) can create a brainlet with 
a simple XML file, no coding needed. People using the same brainlet 
cohoperate in a global annotation. Annotations can be rich, messages, 
images, all allowed using http uipload services so that the actual P2P 
exchange is really just about metadata (rdf) .

We continue with.. a lot of different modules to intelligently tackle 
diffeernt aspects.. a MPEG7Audio DB [4][5] analysis module to extract 
rdf  from music  and reply to acoustic queries, a textual analysys 
module [6] to extract annotations about messages that are inserted.. so 
to create a network of  rdf annotations (rather than a classical text forum)

its all works in progress of course :-) and not much has been published 
either (unfortunately due to the usual publish/perish/do real work).
However, it is not vaporware at all, the downloadable version works 
showing a basic brainlet (With rich gui) and the P2P engine . Version 
0.2 is coming out fairly soon (realistically, end of the year) where all 
the above mentioned features (signing and trust, XML based brainlets, 
mpeg7 and textual analisys modules). Actually the're alrady in the CVS.. 
but time is needed for a real realease.

Problems? plenty, starting from my ph.d being over, funds being out ;-)  
anyway.. those who are interested please join in, its open source and 
we're very open to cohoperations.

P.S. About testing it in practice, i'd suggest people to wait the 0.2 
and the  official announcement. on these lists.
