I am working on a nightowl project to harvest, process, and provide useful financial RDF to the public, free of charge. How do I allow others to query this data and, more importantly, refer to nodes in this data in a way that is reliable... without saturating my server with requests?

Some resources I have been checking out:

Distributed querying on the semantic web
Detailed discussion on the www-rdf-interest list.

RDF Peers [PDF]
A continuation of ISI's MAAN [PDF] concept.

Edutella Project
Uses JXTA to distribute RDF data and queries.

RDF Query, distributed...
Search Mesh Topology
Dan Brickley's early discussions.

FeedMesh
For blog update notification, hopefully relieving us of the regular RSS pounding in the near-future. Spotted today by Danny Ayers and others.
