what would the custom front controller or RSS/SML syntax do? the key it seems to me is the last line of your last post that suggested posting of new comments would be done via a simple post request within the flash app. When that occurs, it seems to me, the empty new comment box with any existing comments would list below the flash app. The only missing element is the number of comments for each video that should appear within the flash app. And this could be determined from the SQL database. Does this make sense?
thanks,
