Hi,
it would be possible to load your Flash as plugin over the pano to control,
(just with: <plugin name="myplugin" url="myplugin.swf" />)
but there is no AS2 interface in krpano!
so to communicate from a AS2 plugin to AS3 krpano, you would need a AS3 plugin between them for communications,
theoretical it should work in this way:
AS2 plugin <=> LocalConnection <=> AS3 plugin <=> krpano
but I think that will be more complicated than direct using AS3
for a simple Flash CS3 (AS3) example have a look here:

best regards,
