I put together a detailed follow-up on the KISSmetrics/Hulu respawning mechanisms outlining exactly how they work (although this is probably pretty basic for most the audience here).

Details here: http://ashkansoltani.org/docs/respawn_redux.html

Feel free to send comments/suggestions.

Also nikcub - very enlightening about the Last-Modified header! It reinforces my point that the solution to all this might not be technical but require policy guidance as to best practices, etc.
