As I read up on yesterday's hype of tagging it kind of struck me that nobody is using tagging as means to locate interesting content in p2p networks. There are quite some papers out there that try to elaborate tomorrow's p2p networks but the idea of tagging seems to be left out.

That should be enough for now. This will be filed in the as-soon-as-I-get-time-to-implement-department.

If anyone knows wether this has Already Been Done (tm), please contact me through the usualy channels. If you are interested in Implementing this, feel free to do so.
