you will find the currently running recordings (and "scraps") in the "staging" subdirectory.
This directory will hold recordings of complete talks.
The filenames in the staging directory contain a timestamp, which denotes the time the recording started.
If the stream was interrupted you will find multiple files for the same talk in the staging directory.
The Schedule: http://events.ccc.de/congress/2011/Fahrplan/
Rsync is also available: rsync://28c3-rsync.ex23.de/streamdump
