[Cubicweb] Decentralization & Multi-source

Hi list,

The broad question : can the multi-source feature promote and render 
functional the decentralized internet ?

The web2.0 model right now offers centralized servers which offer 
services on a proprietary software which community functionality. The 
open source movement has alternatives for most of these online services 
but often you loose the community/social side of things (unless you host 
a multiuser instance which goes back to the centralized model).

Let's take an example : http://www.delicious.com 
<http://www.delicious.com/> bookmark with a social twist. The added 
value of using the central/community approach is that it suggests tags 
for the URL you are bookmarking, you can see the number of times it's 
been bookmarked and when you search your bookmarks you'll get 
suggestions from other user's bookmarks. When you try to leave delicious 
you will find scuttle [1] or semantic scuttle [2] which has basic 
functionality. How difficult would it be for two (or more) cubicweb 
instances to register each other and aggregate these informations ?

The exception of the "isolated web application" that is emerging is 
status.net (twitter open source clone). With status.net you can host 
your own microblog and subscribe to other self-hosted microblogs. That 
way, you control your personal data but are still connected to the web 
of other services.

Would this kind of registration involve multi-source ? Or some other 
technology is preferred ? Linked Data ? I know that right now 
multi-source is configured in the files, how far are from a modification 
of that directly in the web app ?

The bonus question would be how feasible would it be to get a small 
CubicWeb application to run on a low-CPU low-energy embedded device such 
as a plug computer ? For inspiration see http://www.plugcomputer.org/ 
and http://wiki.debian.org/FreedomBox
