JOOST is not so mutch different from other classic P2P networks. Primary goal is to distribute content at high bandwidth with low (or even no) static resources. Hardly centralized on "fresh" content.

The main focus here is - as you mentioned - on retrieval: seek and find information. The simplest form is finding one specific file to download. One of the more complex is: How can I learn to manage Posers lights?

Xlink may help building usefull search results (see www.w3.org/TR/xlink/).

The second focus is to remember any data inserted into the network. The oldest Message, the very first tip how to use Poser may help out someone who installs Poser the first time tomorrow. The very first geometry used in Poser may be of interest for somebody. But, where is it? Who did it?

I know, this is hard thinking for all the people hunting for new content every day :)
