That's indeed something i'd like to do.
But it means re-coding all the graphicals layers from scratch, so it's kind of a long shot. I'd like to do it, but i honestly can't tell when i'll find the time to do it ( baby n°1 incoming very soon ).

But. As for the second part of your sentence, being "i'd like to share/consult sessions with others" : This may not have to involve a online replayer.
I could simply design a online space where people could simply "post" sessions that anther guy could download and load into the existing replayer.

Or may be a bit better : shared session could be displayed as "links" that when clicked automatically run the replayer and load the session.

I'm definetly gonna think about this.
