I didn't think to describe what log.io is in the first place.  Sorry.

It's a node.js app that just listens for log events.  Anyone connected via the web UI will have those events streamed to them.  So, its basically a debugger.  It does not store logs, or anything fancy.

But... in combination with this codec here, it's a fantastic little utility for tweaking configurations and watching the result.  You should check it out if you've not already.. http://logio.org
