Malte,

What about the EC2 AMIs we made, basically, we even pay for a DBpedia 
snapshot [1] (meaning no loading, just mount and go).

We provide a simple loader script and VAD package Linked Data Deployment 
[2] via your own Virtuoso instance (you can also get Virtuoso Open 
Source Edition via most Linux Distros post KDE 4 release).

2.

.


We are also going to release a data sync and replication engine for RDF 
that basically allows you to keep subscribers in sync with publishers 
(directly or via hubs).
