Integrated recording
The ability to record an as live program as if it were (say) 10am at 7:30pm.
PlayIt Live would behave as if you were live at that time and record the result (in much the same way as a stream would be produced). The format (MP3, WAV etc.) would be selectable and there would be an associated cue file for the metadata for the material played (as it would have been streamed).
If the resulting file were to be later played out using a PlayIt Live system all metadata would be produced as if all the pre-recorded items were being played out live.
