FlashPanos

I would like to specify a varying entry point into a pano. I have a related set of panos that include two floors of a building and an exterior (outdoors) pano. Since there are two sets of staircases, and two exit doors, it's possible to
- enter either floor from two separate places
- go to the outside spaces via two exits

I have one XML file for each floor and one for the outside. This causes a problem: launching a pano always goes to the "onStart"-specified preview space. But I want to pick which space to enter from the HTML file (or the openURL call from the XML).

It would be REALLY nice to be able to specify which space is loaded in the onStart routine.

I COULD duplicate each pano in its own HTML file and separate XML files, differing only in their onStart call, but this seems like a hack, not an elegant solution.

I imagine it would require adjusting the ModuleLoader file to allow an extra parameter, like
new SWFObject("ModuleLoader.swf?xml=outside.xml&onStart=preview_backdoor
or
onClick="openURL:tour_lowerlevel.php,_self,preview_backdoor"
and etc.

Can anyone suggest a solution, such as code to add this ability to ModuleLoader? I'm not a flash expert.
